    A series of OEGylated poly(γ-benzyl-l-glutamate) with different molecular weight and narrow molecular weight distribution were prepared from triethylamine initiated ring-opening polymerization (ROP) of OEGylated γ-benzyl-l-glutamic acid based N-carboxyanhydride. They exhibited a reversible UCST-type phase behavior in various alcoholic organic solvents with a UCST-type transition temperature (Tpt) in the range of 16.0–66.3 °C, which was highly depended on the solvent, polymer concentration, side- and main-chain length.

    A method was developed for the synthesis of cyanoacrylated polydimethylsiloxane (PDMS-CA) by the use of various molecular weight PDMS carrying SiH functions. Homonetworks of PDMS-CA and conetworks of PDMS-CA/2-octyl cyanoacrylate were prepared by polymerizing the cyanoacrylate groups. The chemical attachment between PDMS-CA and porcine skin was tested. A dry conformal coating was formed on the skin which could not be removed without damaging the tissue.

  3. Photo-triggered microgel aggregation using o-nitrobenzaldehyde as aggregating power source

    The photo responsive microgel aggregating system is constructed utilizing cationic and anionic gels, and o-nitrobenzaldehyde, which reacts and releases protons in response to UV light. Also, the shapes of the resultant microgel aggregations are regulated due to masking. Additionally, the difference of the thermal responsive property between the resultant microgel aggregation and bulk gel is evaluated.

  4. Polytriacetylenes bearing directly attached functional groups with tunable physical and electronic properties

    Keda Hu and Yang Qin

    Article first published online: 24 NOV 2015 | DOI: 10.1002/pola.27989

    Polytriacetylenes (PTAs) having aromatic substituents directed attached to the main-chain double bonds were prepared, for the first time, by a palladium catalyzed oxidative coupling reaction, which displays tunability in polymer electronic and physical properties.

  5. Degradable precision polynorbornenes via ring-opening metathesis polymerization

    The potential use of dioxepins in ring-opening metathesis polymerization (ROMP) as building blocks of sequence-controlled polymers is evaluated. It is shown that as a result of their low reactivity, dioxepins cannot undergo homopolymerization; however, in the presence of norbornenes they can copolymerize. Therefore, when an excess of dioxepins is present in the ROMP of norbornenes, some sequence control is achieved. Additionally, the copolymers are partially degradable due to the labile dioxepin acetal, resulting in lower molecular weight polynorbornenes.
