Terpolymerization of glycidyl octanoate,carbon dioxide with propylene oxide was carried out using ternary rare-earth-metal coordination catalyst.IR,NMR and DSC results confirm the target polymer was a novel terpolymer.The glass transition temperature of the resoluting terpolymer decreased with increasing flexible glycidyl octanoate units,from 39.6 ℃ of carbon dioxide-propylene oxide copolymer to-12.30 ℃ of carbon dioxide-glycidyl octanoate copolymer,whereas the elongation at break at 20 ℃ increased from 31.0% to 983.9%.Introduction of 5.6% glycidyl octanoate unit into the terpolymer may raise the elongation at break to 481.1%,whereas the tensile strength maintains as high as 24.9 MPa.
