Polymer coatings with improved adhesion properties on metallic surfaces

摘要

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.
