SYNTHESIS OF HYDROPHOBIC ORGANOTIN COPOLYMER FOR ANTIFOULING PAINTS

Organotin based paints are very effective in combating fouling of marine vessels, but their toxicity to non-target marine organisms has caused environmental concern. It is therefore desirable to reduce the rate of release of organotin to the minimum required for the maintenance of antifouling activity. This document reports on research that was undertaken to explore the possibilities of reducing the release rate of copolymer paints by increasing their hydrophobicity. An attempt was made to achieve this effect by the synthesis and esterification of terpolymers of methacrylic acid (methyl methacrylate and butyl methacrylate). The degree of esterification of the final product deviated considerably from the 96-98% desired, however, because of difficulties involved in the analytical titration methods.
