摘要：
A carboxylate component is introduced into an alkali metal initiated polymer by means of a sequence in which an epoxy compound is reacted with the polymer followed directly by contact with a cyclic acid anhydride to produce a polymer composition having a carboxylate salt group. The resulting composition can then be hydrolyzed to produce carboxy-containing polymer which is useful in applications such as sheet molding compounds.
