摘要： In various embodiments, the present invention is directed to terpolymers of carbon monoxide (CO), olefins (alkenes), and epoxides, as well as related methods and catalysts for their making and use. These terpolymer chains are comprised of ketone repeat units, ester repeat units, and ether repeat units. The additional presence of the ester repeat units and ether repeat units have the effect of lowering terpolymer melt temperature relative to that of similar polyketone, thus separating melt temperature from decomposition temperature, making it suitable for melt processing. In a single reaction mixture, the same metal catalyst that polymerizes CO with olefins also incorporates epoxide monomers into the terpolymer in the form of ester or ester and ether linkages. As a part of the terpolymer chain, the ester groups can undergo hydrolysis, rendering these terpolymer compositions hydrolytically degradable.
