Abstract

Biodegradable and biocompatible polyesters, obtained from renewable plant materials, are of great interest due to their use in various industries. The kinetics of anionic ring-opening polymerization (ROP) of α-angelicalactone (αAL) initiated by sodium alcoxides and aluminum isopropoxide has been studied. The kinetics of the process is described by the first order equation in terms of αAL concentration. An increase of the initiator concentration increases the first order rate constant and the αAL conversion, but reduces the molecular weight of the resulting polymers. The maximum αAL conversions (≥0.99) and molecular weights of polymers (26000–29000) were obtained in non-polar solvents, toluene and carbon tetrachloride, and in the bulk at 373–403 K for 60–250 hours
