Method of manufacturing the end acrylic-modified polybutadiene or terminal acrylic-modified hydrogenated polybutadiene and compositions containing them

摘要

(Summary) The present invention is to provide a method without using an organic tin compound, to produce a terminal acryl-modified hydrogenated polybutadiene or polybutadiene-modified acrylic-terminated not cloudy. Diisocyanate compound represented methacrylate, formula (II), and manufacturing method of the present invention, the polybutadiene having a hydroxyl group at the polymer terminal which is represented by formula (III) or acrylate of formula (I) or wherein the reaction is carried out in the presence of at least one selected from tetra-alkoxy zirconium compound and an organic bismuth compound, and hydrogenated polybutadiene.
