Characterization of Bioactive Organotin Polymers: Fractionation and Determination of MW by SEC-GFAA

Organometallic polymers (OMP’s), incorporating biocidal triorganotin moieties, chemically bonded to carboxyl groups pendant along polymer chains, are undergoing intensive development as longterm controlled-release, marine antifouling agents.1 Materials in this general class have been prepared by copolymerizing methyl-methacrylate and organotin-substituted methacrylates in a free radical initiated process.2 The polymers are incorporated within a polymeric binding substrate and coated over surfaces that are to be exposed to a marine-service environment. Tin-containing fragments tailored3 to prevent build-up of fouling micro-organisms4 are slowly leached out of the coating.5 The protective mechanism is not necessarily a simple chemical or physical process, and the macromolecular materials break down over a period of years.1,2
