Disclosed herein are an olefin copolymer having a functional group, which comprises a structural unit (a) derived from ethylene, a structural unit (b) derived from an α-olefin having 3 to 12 carbon atoms, and a structural unit (c) represented by the following general formula (1), and has an intrinsic viscosity [η] of 0.1 to 10 dl/g as measured in decalin at 135°C, a production process thereof and a rubber composition containing the copolymer ;
wherein X1 and X2 mean, independently of each other, a hydrogen atom, a hydrocarbon group or the following specific functional group, at least one of X1 and X2 is the specific functional group, R1 and R2 denote, independently of each other, a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms, one of R1 and R2, which is bonded to a carbon atom to which the specific functional group is bonded, is the hydrocarbon group having 1 to 10 carbon atoms, and n stands for an integer of 0 to 2;
Specific functional group:
a functional group selected from the group consisting of a hydroxyl group, a hydrocarbon group to which a hydroxyl group is bonded, a carboxyl group, a hydrocarbon group to which a carboxyl group is bonded, a primary or secondary amino group, a hydrocarbon group to which a primary or secondary amino group is bonded, a quaternary ammonium salt of a primary or secondary amino group and a hydrocarbon group to which a primary or secondary amino group is bonded, an amide group having at least one active hydrogen atom bonded to a nitrogen atom, a hydrocarbon group to which such an amide group is bonded, and an imide group composed of X1 and X2 and represented by -CO-NH-CO-.
