THERMOPLASTIC POLYMER HAVING POLAR GROUP, USE THEREOF, AND UNSATURATED COMPOUNDS HAVING POLAR GROUP

摘要

The present invention is intended to provide a polar group-containing thermoplastic polymer having high adhesion to metals and polar polymers, uses thereof and a polar group-containing unsaturated compound. The polar group-containing thermoplastic polymer is one obtained by graft modifying a thermoplastic polymer with at least one kind of a polar group-containing unsaturated compound represented by the following formula (I): A-X-R<2>-(Y)p-R<1> wherein A is a group containing a double bond, X is -COO-, -OCO-, -CO-, -O- or the like, R<2> is a divalent group containing a carbon atom or a single bond, Y is -CO-, -COO-, -OCO-, -O- or the like, p is 0 or 1, R<1> is a polar group selected from a carboxylic anhydride group, an epoxy group and the like or an alkyl, cycloalkyl or aryl group containing a polar group, and the bond chain linking the double bond in A to the polar group in R<1> is constituted of 6 or more atoms.
