ABSTRACT:
Copolymers are produced when a 4-vinyl-1,3-dioxolane monomer is copolymerized with an imidized maleic anhydride (for example, maleimide) monomer in the presence of a free radical initiator. Alternatively, a maleamic acid or maleimide functionality may be introduced into a copolymer containing a 4-vinyl-1,3-dioxolane and maleic anhydride by introducing a primary amine into the reaction mixture. Also, the dioxolane reactant may be introduced into the polymer by reacting 3,4-epoxy-1-butene in a ketone reaction solvent. The structure and composition of the product copolymer are controlled by both the sequence and conditions of the reaction. Products of this invention can be cast as clear films and can also be used as reactive polymers.
