  1. Tuning the LCST of poly(2-cyclopropyl-2-oxazoline) via gradient copolymerization with 2-ethyl-2-oxazoline

    Mathias Glassner, Kathleen Lava, Victor R. de la Rosa and Richard Hoogenboom

    Article first published online: 22 AUG 2014 | DOI: 10.1002/pola.27364

    A series of P(c-PropOx-grad-EtOx) gradient copolymers were prepared by living cationic ring opening polymerization of 2-cyclopropyl-2-oxazoline and 2-ethyl-2-oxazoline. All copolymers showed a reversible LCST transition in aqueous solution. The cloud point temperature (TCP) decreased linearly with increasing mol fraction of c-PropOx, allowing accurate tuning of TCP over a wide temperature range. Surprisingly, the glass transition temperature of all copolymers were lower than those of the homopolymers indicating poor interchain miscibility.

  2. Synthesis and characterization of a biodegradable ABC triblock terpolymer as co-delivery carrier of doxorubicin and DNA

    A new kind of cationic ABC triblock terpolymer PEEP-b-PCL-b-PDMAEMA has been successfully prepared via a combination of two-step ring-opening polymerization and atom-transfer radical polymerization reactions. The chemical structures, self-assembly behavior, in vitro enzymatic degradation, cytotoxicity, and pH-dependent controlled release of encapsulated DOX were investigated in detail. In addition, the study by a live cell imaging system further demonstrated that the polymer/DOX/DNA polyplexes could efficiently co-deliver DOX and GFP–DNA into HeLa cells, indicating that they may find potential applications for combinatorial cancer therapy.

  3. Modified soybean oil as a reactive diluent: Synthesis and characterization

    Priyanka P. Nalawade, Brinda Mehta, Coleen Pugh and Mark D. Soucek

    Article first published online: 22 AUG 2014 | DOI: 10.1002/pola.27352

    Soybean oil was modified in two steps: (1) conjugation of soybean oil, (2) Diels-Alder addition with 3-(trimethoxysilyl)propyl methacrylate, 2,2,2-trifluoroethyl methacrylate and triallyl ether acrylate. 13C-1H gHSQC NMR spectra helped confirm the formation of a cyclohexene ring in all reactions, indicating a Diels-Alder addition. The diluent efficiency of modified soybean oil was evaluated in long oil alkyd formulation. Triallyl ether functionalized soybean oil resulted in the highest reduction in the viscosity of the alkyd formulations.

  4. Smart photoluminescent nanohybrids based on CdSe quantum dots capped with multidentate thiolated pH-responsive and thermoresponsive polymers for nanosensing

    Marta Liras, Elena Peinado, Pedro Cañamero, Isabel Quijada-Garrido and Olga García

    Article first published online: 22 AUG 2014 | DOI: 10.1002/pola.27358

    Well-defined thermoresponsive polymers obtained by the atom transfer radical polymerization (ATRP) of MEOnMA (n = 2, 3, or 8) with small ratios of a thiolated comonomer (AcSEMA) can replace the hydrophobic trioctylphosphine oxide capping of CdSe quantum dots (QDs). After ligand exchange, the mild hydrolysis of the acetylthiol group into thiol is the key to enhance the QD luminescence. These copolymers endowed the final materials with their thermoresponsive and amphiphilic properties. The hybrids showed good water dispersability, lower critical solubility temperature around body temperature and, the most important, an abrupt increase of the fluorescence emission when the polymer collapses at acid media.

  5. Photo-induced thiol-ene polysulfide-crosslinked materials with tunable thermal and mechanical properties

    So Young An, Dong Geun Lee, Ji Won Hwang, Kyung Nam Kim, Joon Hyun Nam, Hyun Wook Jung, Seung Man Noh and Jung Kwon Oh

    Article first published online: 22 AUG 2014 | DOI: 10.1002/pola.27353

    A versatile and effective approach is reported utilizing high-molecular-weight methacrylate copolymers, with pendant thiol and vinyl groups (MCPsh and MCPenes), to modulate the thermal and mechanical properties of photo-induced thiol-ene crosslinked materials.
