Antifouling paint

The undesirable swelling exhibited by biologically active copolymers wherein a portion of the repeating units exhibit a triorganotin moiety (R.sub.3 SN--) is reduced by incorporation of a cross-linking agent into the copolymer. The physical and chemical properties of the cross-linked copolymers make them more suitable for use as biocides particularly antifouling toxicants, than polymers described in the prior art.
