A range of poly(ethylene glycol) (PEG)-based polyacrylate networks with two different topological properties were synthesized by photoinitiated free-radical polymerization and analyzed by mechanical, chromatographic, and NMR methods. Comparison betwe

Both enantiomers of 1-2H-1-octanol were obtained by the enzymatic reduction of deuterated octanal in the presence of alcohol dehydrogenases (ADH) (ADH-T or ADH-LB) as the biocatalyst in good yield, purity, and enantiomeric excess (>95%). The cofactor

The surface functionalization of macroporous polyHIPE (pHIPE) was achieved by Huisgen-type 'click' chemistry. In the first step a 600-800 nm thick layer of poly(glycidyl methacrylate) (pGMA) was grafted from the pHIPE surface by atom transfer radical

We investigated the functionalization of polymers with pedant ester groups by enzymatic transesterification. By detailed NMR analysis we have shown that while the monomer can be enzymatically modified, surprisingly no reaction was obtained upon polym

Enzymatic grafting of caprolactone was carried out from poly[styrene-co-(4-vinylbenzyl alcohol)] containing 10% hydroxyl functional monomer and compared with the grafting of vinyl acetate. A molecular weight increase due to the grafting of polycaprol

The enzymatic synthesis of polyesters by ring-opening polymerization (ROP) and polycondensation in three ionic liquids, i.e., [bmim][Tf2N], [bmim][PF6] and [bmim][BF4] was investigated. For the enzymatic ROP of e-caprolactone it was found that [bmim]

The synthesis of novel diblock copolymers consisting of a semifluorinated block of poly(1H,1H,2H,2H-perfluorooctyl methacrylate) (PFOMA) and a hydrocarbon block of polycaprolactone (PFOMA-b-PCL) was achieved by the combination of enzymatic ring-openi

We report the ring-opening polymerization reaction of e-caprolactone in supercritical carbon dioxide (scCO2) using an enzyme catalyst, Lipase B from Candida antarctica supported on macroporous beads (Novozym-435). Ring-opening polymerization of lacto
