New Coploymers Derived from Vinazene and other Monomers

Technology #1736

Background

Vinyl dicyanoimidazoles are a family of substituted imidazole compounds which can be made from the oxidation of reaction products synthesized by carefully controlled Schiff base reactions of diaminomaleonitrile with several conjugated aldehydes. Vinyl dicyanoimidazoles and their derivatives can polymerize to form homopolymers which exhibit desirable characteristics such as elevated glass transition temperature and flammability resistance. Incorporation of vinyl dicyanoimidazoles and their derivatives into copolymerized materials with various existing monomeric compounds would be desirable. However, high capital costs and stringent controls over feedstocks and processing may be limiting.

Technology

Researchers at the University of Michigan have developed copolymers which incorporate substituted imidazoles, particularly cyano-substituted imidazoles, into the respective copolymeric matrix. The incorporated compound, 4,5-dicyano-2-vinylimidazole or its derivatives, present initially as a monomer or homopolymer, but may also be a copolymer with other compounds deemed useful to the make-up of the final copolymeric compound.
