WebBiodegradable and hydrophilic functional polyesters were synthesized enzymatically using xylitol or d-sorbitol together with divinyl adipate and lipase B from Candida antartica (CAL-B). The resulting polyesters had pendant OH-groups from their sugar units which were esterified to different degrees with stearic acid chloride. The structure and the degrees of … WebFeb 7, 2024 · The crystallization and melting behaviors of the synthesized unconcatenated and unknotted cyclic PCLs were investigated by DSC, POM and X-ray. The DSC and POM characterized crystallization behaviors of the cyclic PCLs showed that the half-time of crystallization and spherulite growth rate related to the molecular weights.
