Highly branched linear-comb random copolyesters of ε-caprolactone and δ-valerolactone: Isodimorphism, mechanical properties and enzymatic degradation behavior

In this work, a series of highly branched linear-comb random copolyesters of ε-caprolactone (CL) and δ-valerolactone (VL) with high molecular weight and narrow distribution in various compositions were successfully synthesized. The composition-dependent microstructure, thermal and mechanical properties, and enzymatic degradation behavior of the resulting copolyesters were investigated systematically. The cocrystallization behavior was observed...
