- Synthesis of functional block copolymers and terpolymers containing polyglycidyl methacrylate blocks
Susanne Höhne and Petra Uhlmann
Article first published online: 22 DEC 2014 | DOI: 10.1002/pola.27491
Triblock terpolymers with a glycidyl methacrylate block, a hydrophobic methyl methacrylate, and a latent hydrophilic tert-butyl acrylate block are prepared by ATRP. The terpolymers show narrow molecular weight distributions and the polymerization process is well controlled if the polymers are built up from the acrylate block. As shown by differential scanning calorimetry, the single blocks in the terpolymers show different glass points depending on length.
- Synthesis of polyisocyanurates by thermal rearrangement of polycyanurates

Article first published online: 22 DEC 2014 | DOI: 10.1002/pola.27492
Polycyanurates prepared from 2,4-dichloro-6-methoxy-1,3,5-triazine and bisphenol monomers are successfully rearranged to polyisocyanurates with high temperature thermal treatment in the presence of a small amount of tetrabutyl ammonium bromide as a catalyst in an argon atomosphere. The resulting polyisocyanurates produce the transparent and amorphous films and show a good thermal stability with 5% weight loss temperature above 340 °C in nitrogen and the glass transition temperature above 210 °C.

Article first published online: 22 DEC 2014 | DOI: 10.1002/pola.27493
Emitting polyfluorenes with pendant ethoxysilyl groups were prepared. Hydrolysis and polycondensation of tetraethoxysilane and silanol-terminated polydimethylsiloxane in the presence of the ethoxysilyl-functionalized polyfluorenes gave transparent luminescent silicones. Fluorescent spectra of these silicones revealed that emitting polymers were dispersed homogeneously in the matrix of silicone without aggregation. Since alternated incorporation of arylene moieties in fluorene-based π-conjugated polymers leads to the tunability of the emitting properties, fluorene/silicone hybrids are interesting candidates for various optical materials.
- Hydrogel synthesis by aqueous Diels-Alder reaction between furan modified methacrylate and polyetheramine-based bismaleimides
Clara García-Astrain, Itxaso Algar, Alessandro Gandini, Arantxa Eceiza, María Ángeles Corcuera and Nagore Gabilondo
Article first published online: 22 DEC 2014 | DOI: 10.1002/pola.27495
Chemically crosslinked hydrogels have been prepared using Diels-Alder reaction in aqueous media between furan modified poly(2-aminoethyl methacrylate) and Jeffamine®-based bismaleimides.
- Efficient solvent-free alternating copolymerization of CO2 with 1, 2-epoxydodecane and terpolymerization with styrene oxide via heterogeneous catalysis
Ying-Ying Zhang, Ren-Jian Wei, Xing-Hong Zhang, Bin-Yang Du and Zhi-Qiang Fan
Article first published online: 22 DEC 2014 | DOI: 10.1002/pola.27497
The well-controlled solvent-free alternating copolymerization of 1, 2-epoxydodecane and CO2 was reported by using nanolamellar Zn-Co(III) double metal cyanide complex catalyst. By introducing styrene oxide with electron-withdrawing phenyl group into 1, 2-epoxydodecane-CO2 copolymerization system, a new random terpolymer was produced with single glass transition temperatures (Tgs) in a wide range from 3 to 56 °C, which might be potentially used as biodegradable elastomers or plastics.
