Copolymers of omega-pentadecalactone (PDL) with epsylon-caprolactone, valerolactone, dioxanone and trimethylenecarbonate synthesized by biocatalysis show rather uncommon crystallization behavior, namely cocrystallization of the monomer units that leads to highly crystalline copolymers over the whole composition range. Hydrophilic/hydrophobic balance can be adjusted by a suitable choice of the comonomer and of composition, leading to materials with tunable hydrolytic degradation rate for environmental and biomedical applications. Copolyestercarbonates, copolyesteramides and polyol-containing copolyesters synthesized by lipase-catalysed polycondensation show strongly composition dependent physical properties, that can be easily tailored by composition control and cover the whole range from hard solid materials down to gluelike substances

Abstract
Copolymers of omega-pentadecalactone (PDL) with epsylon-caprolactone, valerolactone, dioxanone and trimethylenecarbonate synthesized by biocatalysis show rather uncommon crystallization behavior, namely cocrystallization of the monomer units that leads to highly crystalline copolymers over the whole composition range. Hydrophilic/hydrophobic balance can be adjusted by a suitable choice of the comonomer and of composition, leading to materials with tunable hydrolytic degradation rate for environmental and biomedical applications. Copolyestercarbonates, copolyesteramides and polyol-containing copolyesters synthesized by lipase-catalysed polycondensation show strongly composition dependent physical properties, that can be easily tailored by composition control and cover the whole range from hard solid materials down to gluelike substancesI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
