Enzymatic Synthesis and Characterization of Novel Polycarbonates Derived from 5-Allyloxy-1,3-dioxan-2-one and 5,5-Dimethyl-1,3-dioxan-2-one
摘要:
Novel polycarbonates from 5-allyloxy-1, 3-dioxan-2-one (ATMC) with 5, 5-dimethyl1, 3-dioxan-2-one (DTC) were successfully synthesized for the first time using immobilized porcine pancreas lipase (IPPL) as catalyst. The resulting copolymers were characterized by IR,1HNMR, 13C NMR and GPC. The molecular weight (Mn) of the copolymer with molar feed ratio of 10:90(ATMC:DTC) was 9300 and the polydispersity was 1.31, while the Mn increased to 14300 and polydispersity of 1.25 with the feed ratio of 50:50. Moreover, the composition of the copolymers agreed well with the monomer feed.
