摘要：
The present invention provides a method for producing a terminal acrylic-modified polybutadiene or terminal acrylic-modified hydrogenated polybutadiene that does not become white and turbid, without using an organotin compound. The production method of the present invention comprises reacting an acrylate or methacrylate represented by formula (I), a diisocyanate compound represented by formula (II), and a polybutadiene or hydrogenated polybutadiene having a hydroxyl group at a polymer terminal, represented by formula (III), in the presence of at least one selected from an organobismuth compound and a tetraalkoxyzirconium compound.
