  1. Selective interactions of a high-molecular-weight polycarbazole with different commercial nanotube samples

    Nicole A. Rice and Alex Adronov

    Article first published online: 9 JUL 2014 | DOI: 10.1002/pola.27292

    The interaction of a high molecular weight polycarbazole with single-walled carbon nanotubes (SWNTs) was found to be selective for semiconducting SWNTs. This polymer was able to disperse commercial raw HiPCO, purified HiPCO, and CoMoCat SWNTs. Annealing of the purified HiPCO SWNTs led to a dramatic improvement of spectroscopic properties

    Glyco(poly(2-oxazoline)s) functionalized with Pt(II) units for targeted tumor applications are synthesized by post-polymerization modification of poly(2-ethyl-2-oxazoline-block-2-(3-butenyl)-2-oxazoline) using thiol-ene photoaddition. The hemolytic activity, induction of erythrocyte aggregation as well as the cytotoxicity against mouse fibroblast L929 cells, human embryonic kidney cells HEK 293, and human hepatocytes HepG2 is studied and compared with cisplatin.

  3. ABA triblock copolymers from two mechanistic techniques: Polycondensation and atom transfer radical polymerization

    Natalia A. Agudelo, Andrea M. Elsen, Hongkun He, Betty L. López and Krzysztof Matyjaszewski

    Article first published online: 9 JUL 2014 | DOI: 10.1002/pola.27300

    A series of ABA triblock copolymers were synthesized utilizing two polymerization techniques, polycondensation and atom transfer radical polymerization (ATRP). The choice of polymerization mechanisms results in block copolymers with unique molecular weight distributions the center of these triblock copolymers are disperse, resulting from polycondensation while the outside blocks have narrow molecular weight distribution due to the control afforded from ATRP.

  4. Synthesis, self-assembly, and thermosensitivity of amphiphilic POEGMA-PDMS-POEGMA triblock copolymers

    Guiyou Wang, Mengli Chen, Shiqing Guo and Aiguo Hu

    Article first published online: 9 JUL 2014 | DOI: 10.1002/pola.27299

    A well-defined biocompatible amphiphilic POEGMA-PDMS-POEGMA triblock copolymer was synthesized by atom transfer radical polymerization using α,ω-dibromo polydimethylsiloxane as a macroinitiator. The copolymers had good thermosensitivity, with reversible and sharp phase separation. The copolymers had low critical micelle concentration values and easily self-assembled into spherical micelles in aqueous solution.

  5. Synthesis and self-assembly of thermosensitive double-hydrophilic poly(N-vinylcaprolactam)-b-poly(N-vinyl-2-pyrrolidone) diblock copolymers

    Xing Liang, Veronika Kozlovskaya, Christopher P. Cox, Yun Wang, Mohammad Saeed and Eugenia Kharlampieva

    Article first published online: 4 JUL 2014 | DOI: 10.1002/pola.27291

    Novel temperature-responsive double-hydrophilic poly(N-vinylcaprolactam)-b-poly(N-vinyl-2-pyrrolidone) (PVCL-b-PVPON) diblock copolymers are synthesized through the reversible addition-fragmentation chain transfer polymerization. The copolymers became amphiphilic upon heating due to the reversible coil-to-globule transition of PVCL blocks. Remarkably, the PVCL-b-PVPON copolymers perform temperature-induced self-assembly into nanostructures from 70 nm to 200 nm in size with the hydrophobic PVCL blocks shielded by hydrophilic PVPON blocks.
