ABSTRACT:
Carboxylated styrene allyl alcohol copolymers are prepared by reaction of trimellitic anhydride and a hydroxy copolymer under controlled conditions to minimize polyester formation. The hydroxy copolymer is a copolymer of styrene or a substituted styrene and allyl alcohol or methallyl alcohol containing from 1.8 to 10 weight percent hydroxyl. At least one hydroxy group per molecule and preferably 20-80 percent of the hydroxyls of the hydroxy copolymer are reacted with trimellitic anhydride. The carboxylated styrene allyl alcohol copolymers can be used in aqueous or organic solvent solution in adhesive and surface coating applications.
