Poly(ester-anhydrides) were synthesised from poly(L-lactide), poly(D,L-lactide), and poly(e-caprolactone) prepolymers prepared by ring-opening polymerisation of cyclic esters in the presence of 1,4-butanediol or ricinoleic acid as co-initiator. The h

Resorbable poly(ester anhydride) networks based on e-caprolactone, L-lactide, and D,L-lactide oligomers were synthesized. The ring-opening polymerization of the monomers yielded hydroxyl telechelic oligomers, which were end-functionalized with succin

Cross-linked e-caprolactone (CL) and D,L-lactide (DLLA) copolymers with elastic properties were synthesized in three steps. First, the monomers were copolymerized in ring-opening polymerization to obtain telechelic star-shaped oligomers with almost c

The effect of molecular architecture on the properties of crosslinked polylactides was studied. D,L-Lactide-based telechelic oligomers with different numbers of arms were functionalized with methacrylic anhydride. Functionalized oligomers were crossl

The self-reinforcing and hydrolytic degradation of an amorphous poly(ester-amide) (PEA) based on lactic acid have been studied and compared with those of poly-L-lactide (PLLA). The studied PEA-rods were self-reinforced (SR) by solid-state die drawing

Linear and star-shaped polylactides were prepared by using alcohols with different numbers of hydroxyl groups as co-initiators. 1H-NMR analysis of low molecular weight polymers showed that the number of hydroxyl groups initiating polymerisation was n
