Abstract:
1. A method for producing a terminal acrylic-modified polybutadiene or terminal acrylic-modified hydrogenated polybutadiene represented by formula (IV): where: R R R m represents 1 or 2; and PB represents polybutadiene or hydrogenated polybutadiene, the method comprising reacting an acrylate or methacrylate represented by formula (I): with a diisocyanate compound represented by formula (II): and with a polybutadiene or a hydrogenated polybutadiene having a hydroxyl group at a polymer terminal, represented by formula (III): in the presence of a catalytic amount of at least one selected from: where each R 12 independently represents a C1 to C20 alkyl group having a straight chain or a branched chain, and a tetraalkoxyzirconium compound represented by formula (IX): where each R 21 independently represents a C1 to C20 alkyl group having a straight chain or a branched chain.
