Biologically Active Polymeric Coating Materials.

摘要

Over 100organometallic polyacrylates, polyvinyls,polyesters,epoxies,and polyurethanes have been synthesized and are undergoing antifouling performance evaluation in Pearl Harbor,Hawaii,and Miami Beach,Florida. During accelerated aging trials,using a rotating cylinder apparatus,organometallic polymers have demonstrated from 1/2to 1/15the leaching rate of a Navy experimental antifouling coating,formula 1020A. The same organometallic polymers continue to exhibit 100% antifouling effectiveness after up to a 2 1/2-year exposure in the severe fouling climate of Pearl Harbor,Hawaii. Four organometallic polymers have been selected for use in the formulation of experimental antifouling coatings with air-pollution-exempt solvents. Two experimental formulations using one organometallic polymer have been completed and are undergoing panel immersion trials at Pearl Harbor,Hawaii,and Miami Beach,Florida. Acute mammalian toxicity studies of this organometallic polymer have been completed,as well as recommendations for its safe handling by shipyard personnel. (Author)
