Abstract
The present invention is based on a series of acrylic cross-linking agents containing two or more dehydroalanine moieties (H2C═C(NHCOR′)COOR) per monomer. Monomers of the general structure H2C═C(NHCOCH3)COO(CH2)iOO(CH3CONH) C═CH2 with i=4, 5, and 8 can be polymerized or copolymerized under UV-curing conditions or by simple heating above melting point, leading to cross-linked polymeric materials. When polymerized on metallic surfaces, exceptional adhesion is obtained with no need for additional adhesion enhancers.
