Abstract
A series of poly(methyl methacrylate)-g-poly(dimethylsiloxane) and pol y(methyl ethacrylate)-g-poly(trifluoropropylmethylsiloxane) copolymers have been synthesized via the 'macromonomer' method by which monofunc tional polysiloxane macromonomers are copolymerized with methyl methac rylate. The graft copolymers have been characterized by gel permeation chromatography, H-1 n.m.r. spectroscopy and differential scanning cal orimetry. Dynamic contact angle (DCA) analysis afforded advancing and receding water contact angles over 15 days immersion in water. The ini tially hydrophobic polymer surfaces rapidly rearrange in the presence of water to more hydrophilic surfaces. The effects of varying the amou nt and type of siloxane in the copolymer on DCA results are discussed. The fouling and fouling release behaviour of coatings formulated from the graft copolymers have been evaluated in Chesapeake Bay. Fouling a nd fouling release behaviour are discussed in the light of DCA results . (C) 1998 Elsevier Science Ltd. All rights reserved.
