Synthesis and properties of novel aliphatic polycarbonate from carbon dioxide with 1,2-butylene oxide and ɛ-caprolactone

A new degradable aliphatic poly(butylene-co-ɛ-caprolactone carbonate) (PBCL) was synthesized through the terpolymerization of carbon dioxide, 1,2-butylene oxide (BO) and ɛ-caprolactone (CL), a polymer supported bimetallic complex (PBM) was used as a catalyst. The terpolymers prepared were characterized by FT-IR, 1H NMR, 13C NMR, WXRD and DSC. The hydrolysis tests were carried out to appraise the degradability of the copolymers.
