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-R2-(Y)p-R1 (I)
wherein A is a group containing a double bond, X is -COO-, -OCO-, -CO-, -O- or the like, R2 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, R1 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 R1 is constituted of 6 or more atoms.
本发明旨在提供一种含极性基团的热塑性聚合物,具有对金属和极性聚合物的高粘附性,以及其用途和含极性基团的不饱和化合物。所述含极性基团的热塑性聚合物是通过将至少一种由以下式(I)表示的含极性基团的不饱和化合物进行接枝改性而获得的: A-X-R2-(Y)p-R1 (I)其中A是含有双键的基团,X是-COO-,-OCO-,-CO-,-O-或类似的基团,R2是含有碳原子或单键的二价基团,Y是-CO-,-COO-,-OCO-,-O-或类似的基团,p为0或1,R1是从羧酸酐基团、环氧基团等中选择的极性基团,或含有极性基团的烷基、环烷基或芳基,A中的双键与R1中的极性基团之间的键链由6个或更多原子构成。
