      Light and pH sensitive PEG-b-poly(MPC-Azo/DEA) was synthesized via ROP of cyclic carbonate bearing pendant alkynyl group followed by azide-alkyne cycloaddition click reaction with azide-containing compounds Azo-N3 or DEA-N3. The morphological changes of the polymer micelles in response to dual stimuli were investigated. The release efficiency of loaded NR was greatly enhanced by the combined stimuli. Then DOX was loaded into the nanoparticles and the loaded-DOX could be released from these nanoparticles under dual stimuli. The obtained PEG-b-poly(MPC) and PEG-b-poly(MPC-Azo/DEA) showed good biocompatibility and low toxicity against HepG2 cells as well as SMCC-7721 cells. More importantly, the DOX-loaded nanoparticles exhibited good anticancer ability for the two cells.

      Azo-functionalized PS MIPs with specific recognition sites for the florescent template molecule Pyrenebutyric acid were developed by dispersion polymerization. In contrast to NIP, which showed weak excimeric pyrene emission, the MIPs exhibited monomeric pyrene emission clearly demonstrating the difference in location of the readsorbed pyrene butyric acid on the surface in case of NIP and inside cavity in case of the MIP. The azo moiety also offered a handle with which to modify the emission properties of the fluorescent MIP upon irradiation at 360 nm.

      The miniemulsion process is optimized by using a RAFT molecule as both chain transfer agent and (co)stabilizer without premodification of the RAFT agent such as block copolymer. By adjusting the experimental conditions, it is possible to prepare spherical nanoparticles with defined characteristics. The final control and kinetics of the polymerization process under a RAFT mechanism can be regulated by adjusting the final function of the RAFT compound: CTA and/or (co)stabilizer.

      Xinxing Liu, Jitendra S. Rathore, Geraud Dubois and Leonard V. Interrante

      Version of Record online: 15 FEB 2017 | DOI: 10.1002/pola.28522

      Thumbnail image of graphical abstract

      Alkylene- and arylene-bridged cyclolinear polycarbosilanes (CLPCS) with 1,3-disilacyclobutane (DSCB) rings incorporated in the main chain of the polymer were prepared by polycondensation between corresponding di-functional DSCB derivatives and di-Grignard reagents. The phenylene-bridged CLPCS undergoes photochemically induced crosslinking on UV irradiation to form a thermally stable (Td(TGA 5%) = 540 °C), crosslinked, polycarbosilane network, solid. The spin-cast, cured films of these CLPCSs exhibit low dielectric constants and exceptional mechanical properties for applications in electronics, including directly UV-photopatterned low-k dielectrics.

    1. MALDI-TOF MS investigation of the unconventional termination of living polyoxazoline with ammonia

      Karolina A. Kosakowska, Philip Dimitrov, Gangadhar Panambur and Scott M. Grayson

      Version of Record online: 13 FEB 2017 | DOI: 10.1002/pola.28495

      Thumbnail image of graphical abstract

      Well-defined amine terminated poly(2-oxazoline) is a material of potential utility, and its synthesis was attempted by quenching the living cationic ring opening polymerization of 2-ethyl-2-oxazoline with ammonia. MALDI-TOF MS analysis provides evidence that is further supported by NMR and titration experiments for an alternative termination phenomenon yielding a hydroxyethylamino terminal group. Based on the observed data, a mechanistic explanation for the observed 2-oxazoline ring-opening termination is proposed.

    1. Oxygen-mediated polymerization initiated by oltipraz-derived thiones

      Scott R. Zavada, Joseph C. Furgal, Nathan D. Wood and Timothy F. Scott

      Version of Record online: 11 FEB 2017 | DOI: 10.1002/pola.28507

      Thumbnail image of graphical abstract

      The incorporation of a bis-disulfide derivative of oltipraz (bisDS) in model thiol-ene resin formulations affords an in situ generated pyrrolopyrazine-thione. Subsequent exposure of these resins to atmospheric oxygen results in the generation of radicals via a redox cycle, in the presence of both thiol and molecular oxygen, permitting its utilization as an oxygen-mediated initiating system for thiol-ene polymerizations.

      Slow initiation can lead to broadened polymer dispersities and variable sequences in chain-growth polymerizations. Herein, reactive ligands are used to selectively accelerate the precatalyst initiation rate without altering the propagation rate in a Ni-mediated catalyst-transfer polymerization. In addition, a direct method for measuring initiation and propagation rates under authentic polymerization conditions is reported.

      Thumbnail image of graphical abstract

      A series of anion conductive aromatic terpolymer membranes (QPAF-3) containing perfluoroalkylene, alkylene, and ammonium-functionalized phenylene groups without heteroatom linkages in the main chain were synthesized. The presence of the alkylene groups did not practically affect the hydroxide ion conductivity and alkaline stability. The QPAF-3 (3) membrane with optimized terpolymer composition showed high hydroxide conductivity (123 mS cm 1 in water at 80 °C) and chemical robustness of the main chain under accelerated alkaline stability test conditions (1 M KOH for 1000 h at 80 °C).

      RAFT polymerization of both N-acryloylmorphorin and N-succinimidyl acrylate by using a newly synthesized dithiobenzoate-type chain transfer agent bearing hydroxyl groups at both terminals (HECPHD) was carried out. After the acryloylation of the hydroxyl terminals of the obtained polymer, gelation was observed. The results show that activated esters-bearing polymers with hydroxyl groups at both terminals can be used as building blocks for constructing polymeric materials for an immobilization of biomacromolecules.

      Thumbnail image of graphical abstract

      Poly(fullerene)s formed using the atom transfer radical addition polymerization (ATRAP) are explored with quantum chemistry to map their expected electronic behavior with respect to common electron acceptors. Surprisingly, PFs should demonstrate electron affinities and LUMO energy levels close to bis-derivatives, even though only one C60 double-bond is used in PF chain formation. A self-consistent library of PFs is synthesized and correlations between comonomers and structural characteristics are found.

    2. Poly(glyceryl glycerol): A multi-functional hydrophilic polymer for labeling with boronic acids

      Tina Borke, Antti Korpi, Fabian Pooch, Heikki Tenhu and Sami Hietala

      Version of Record online: 26 JAN 2017 | DOI: 10.1002/pola.28497

      Thumbnail image of graphical abstract

      Poly(glyceryl glycerol) (PGG) is prepared by monomer-activated ring-opening polymerization and conjugated to poly(l-lactide) (PLLA) via click reaction. PGG can react with boronic acids to form boronic esters in neutral aqueous solution. This feature is employed to label PGG–PLLA nanoparticles with boronic acid-containing fluorophores. This study demonstrates that glycerol-boronic acid interactions, which are believed to be rather weak in water, yield surprisingly strong bonds in glycerol polymers.

      Thumbnail image of graphical abstract

      A polyamine-based dendritic amphiphile attached on surface of a porous matrix will adopt a Janus-particle-like conformation, and still shows high binding strength to a dye than a comb-like amphiphile does, which is attributed to a topological factor. The resulting adsorbent can eliminate trace dyes in water.
