ALIPHATIC POLYMER HAVING KETONE GROUP AND ETHER BONDING IN MAIN CHAIN, AND RESIN COMPOSITION

摘要

An aliphatic polymer having a ketone group and an ether bonding in its main chain, characterized in that it comprises a structural unit represented by the general formula (1) and a structural unit represented by the general formula (2), wherein Ra and Rb independently represent a substituted or unsubstituted divalent aliphatic hydrocarbon group, Rc represents a substituted or unsubstituted divalent aliphatic hydrocarbon group having an ether bonding in the terminal thereof, or a single bond, n1 represents an integer of 1 or more and n2 represents an integer of 0 or more, provided that n1 + n2 is in the range of 2 to 1000; and a resin composition, characterized in that it comprises a structural unit represented by the general formula (1) as a component. Said polymer preferably contains an ether bonding and a ketone group in a ratio of 0.01 to 100. Said polymer can be substantially comprised of a structural unit represented by the general formula (1) as a recurring unit. The resin composition may further comprises an electroconductive powder.
