Abstract:
Copolymer PCL\|b\|PB\|b\|PCL was successfully prepared by a novel chemoenzymatic strategy coupled with enzymatic ringopening polymerization (eROP) and ringopening metathesis polymerization (ROMP). The chemical structures of the products were characterized by 1H NMR, GPC and DSC. A complete shift of the GPC trace to higher molecular weights illustrates that the copolymer was successfully prepared. 1H NMR data clearly show block in the copolymer is hydrolyzed completely, and a clear shift of the GPC trace to lower molecular weights illustrates that the synthetic strategy is reliability.
Key words: ring-opening metathesis polymerization (ROMP), enzymatic ring-opening polymerization(eROP), chemoenzymatic, block polymer
