    • 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.
    • 被设计成浸没在海洋环境中的物体通过使用基于弹性体的覆盖材料来保护长时间的结垢,其特征在于从制剂中引入的有机金属聚合物有毒物质的输送速率恒定。 该制剂基本上由重量计约44%至约85%的选自氯丁橡胶(聚氯丁二烯)橡胶,天然橡胶和EPD(乙烯 - 丙烯 - 二烯)橡胶的弹性体材料组成; 约7%至约25%的选定填料,抗氧化剂,促进剂,颜料和其它加工化合物,和; 约1%至约48%的含有侧基三正丁基锡的有机金属聚合物,其选自聚(三正丁基甲基丙烯酸甲酯 - 共 - 正丙基甲基丙烯酸甲酯 - 甲基丙烯酸甲酯1:1 :1摩尔比,聚(三正丁基锡甲基丙烯酸酯 - 共 - 甲基丙烯酸甲酯)1:1摩尔比,聚(甲基乙烯基醚 - 共 - 马来酸)的三正丁基锡酯1:1摩尔比和三 与二乙烯基苯交联的聚甲基丙烯酸的正丁基锡酯。
