Abstract

It is an object of the present invention to provide a method for producing a terminal-modified polybutadiene or terminal-modified hydrogenated polybutadiene that does not become colored or white and turbid, without using an organotin compound. The production method of the present invention includes 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 organoaluminum compound and an organozinc compound (with the proviso that zinc naphthenate is excluded).
