Highly porous functional scaffolds were obtained from linear and cross‐linked multifunctional poly(ε‐caprolactone) and poly(L‐lactide). The polymers were synthesized by ring‐opening polymerization of ε‐caprolactone and L‐lactide using poly(but‐2‐ene‐1,4‐diyl malonate) (PBM) as macroinitiator and stannous 2‐ethylhexanoate. The presence of a double bond in each repeating unit of PBM enabled cross‐linking...
A wood hydrolysate derived hemicellulose-rich fraction was functionalized with L-lactide oligomers through a ring opening polymerization mediated grafting-from reaction. The graft copolymer was designed to act as a compatibilizer in hydrolysate/poly(L-lactide) (PLLA) blend films. The PLLA addition improved the tensile behavior of the hydrolysate matrix and this effect was enhanced further by the addition...
The catalytic effect of enzymes in different environments has been compared. Biodegradable polyesters and corresponding nanoparticles have been synthesized by an “eco-friendly” technique; enzyme-catalyzed ring-opening polymerization of lactones in bulk and in an aqueous mini-emulsion. Lipases from Burkholderia cepacia (lipase PS), B. cepacia immobilized on ceramic, Pseudomonas fluorescens and Candida...
