Patent number: 3979354Abstract: Objects which are designed to be submersed or submerged are rendered antiling by using an organotin polymer wherein the tin is chemically combined in or bonded to the polymer. The polymer inhibits fouling of the exposed surface of the object while minimizing the effect on the surrounding environment due to reduced leaching of the organometallic compound from the polymer.Type: GrantFiled: January 31, 1974Date of Patent: September 7, 1976Assignee: The United States of America as represented by the Secretary of the NavyInventors: Edward J. Dyckman, Jean A. Montemarano, Eugene C. Fischer, Robert R. Ressler
