Abstract
Compounds containing both electron donor and electron acceptor functionality are suitable for use in adhesives. The electron donor group is a carbon to carbon double bond attached to an aromatic ring and conjugated with the unsaturation in the ring. The electron acceptor group is a maleimide, acrylate, fumarate or maleate.
Claims4
A compound having the structure
- in which
- Ar is an aromatic or heteroaromatic ring or fused ring having 3 to 10 carbon atoms within the ring structure, in which the heteroatom is N, O or S;
