Objects which are designed to be submerged in a marine environment are prcted from fouling for an extended period of time by the use of elastomeric based covering materials which are characterized by a constant delivery rate of the incorporated organometallic polymer toxicant from the formulation. The formulation consists essentially of, by weight, from about 44% to about 85% of elastomeric material selected from the group consisting of neoprene (polychloroprene) rubber, natural rubber, and EPD (ethylene-propylene-diene) rubber; from about 7% to about 25% of selected fillers, antioxidants, accelerators, pigments, and other processing compounds, and; from about 1% to about 48% of organometallic polymer containing pendant group tri-n-butyltin selected from the group consisting of poly (tri-n-butyltin methyacrylate-co-tri-n-propyltin methyacrylate-co-methyl methacrylate 1:1:1 mole ratio, poly (tri-n-butyltin methacrylate-co-methyl methacrylate) 1:1 mole ratio, tri-n-butyltin ester of poly (methyl vinyl ether-co-maleic acid) 1:1 mole ratio and tri-n-butyltin ester of poly methacrylic acid cross-lined with divinylbenzene.
