Photocross-linking Kinetics Study of Benzophenone Containing Zwitterionic Copolymers.

ABSTRACT: The kinetics of benzophenone (BP) and its derivatives have been widely studied in different solvents by nanosecond laser flash photolysis as well as in the polymer matrix. With the development of functional polymer coating, BP, as well as other photocross-linkers, has been incorporated into the polymer backbone or side chain to form the covalent connection between polymer coatings and substrates, which can improve the mechanical and chemical stability of the coatings. In this work, a series of BP pendent zwitterionic copolymer kinetics were investigated using UV-vis for the first time. Because of the high hydrophilicity of the zwitterionic monomer, the influence of the polymer matrix's polarity on the cross-linking rate was observed. With a higher zwitterionic percentage in the copolymer,
