Abstract
A method for producing esters of hydroxy terminated polybutadiene, including the steps of: (a) providing an anhydride; (b) reacting a hydroxy terminated polybutadiene with the anhydride to form a carboxyl terminated polybutadiene derivative; (c) reacting the derivative with an epoxide. Also a curable composition, including: (a) an ester of hydroxy terminated polybutadiene; (b) a copolymerizable ethylenically unsaturated monomer; and (c) a drier.
