Initiated manufacture of vinyl resins by the suspension resin process at South Charleston, West Virginia. Converted the emulsion polymerization plant to a dispersion resin plant at South Charleston, West Virginia. Expanded the solution polymerization plant at Texas City, Texas. Perth Amboy Bulk Terminal started operation under OTD management. Initiated manufacture of vinyl resins by the suspension resin process at Texas City, Texas under technology license from Wacker Chemie. Expanded the suspension vinyl resin plant at Texas City, Texas, reduced capacity for bulk resins by fifty percent at Texas City, Texas ami discontinued manufacture of sus pension vinyl resins at South Charleston, West Virginia. Union Carbide Corporation representatives met with the Manufacturing Chemists Association to discuss reported acroosteolysis at the B. F. Goodrich Chemical Company plants. Support for an epidemiological study was pledged by Union Carbide Corporation. Discontinued manufacture of vinyl chloride at South Charleston, West Virginia. Expanded the suspension vinyl resin plant at Texas City, Texas. An employee of Union Carbide Corporation at South Charleston West Virginia plant dispersion PVC unit died of liver cancer subsequently diagnosed as angiosarcoma of the liver, a rare type of cancer. Discontinued manufacture of vinyl chloride at Texas City, Texas. The epidemiological investigation of the PVC industry co sponsored through MCA by Union Carbide Corporation showed no confirmed cases of acroosteolysis in any Union Carbide Corporation polymerization plants. Union Carbide Corporation co-sponsored a visit to the U.S.A. by Dr. P. L. Viola to discuss his reported oncogenic effect of vinyl chloride exposure 'to, rats with the Manufacturing Chemists Association Occupational Health Committee. ucc 059707 3 197X 1972 1973 1974 1975 1976 1977 1981 1982 An Ad Hoc Planning Group for Vinyl Chloride Research was formed in MCA under the chairmanship of Mr. R. N. Wheel r, jr., of Union Carbide Corporation. The Group recommended chronic toxicity studies, a metabolism study and an epidem iological study of the effects of vinyl chloride at an estimated cost of $350,000. Union Carbide Corporation agreed to co-sponsor the chronic toxicity and other studies proposed by MCA. Union Carbide Corporation representative, Mr. R. N. Wheeler, along with representatives of MCA, Dow, Ethyl and Imperial Chemical Industries met with Dr. M. Key and Associates of the National Institute for Occupational Safety and Health to discuss the status of the possible vinyl chloride chronic toxicity problem. Union Carbide Corporation supplied the National Institute for Occupational Safety and Health and the Occupation Safety and Health Administration with written testimony and free access to its plants using vinyl chloride. It also reported promptly - the second dea .r of an employee from angiosarcoma of the liver. Union Carbide Corporation through Organization Resources Counselors co-sponsored an epidemiological study of the PVC fabricating industry as well as provided access to its records for the study. Union Carbide Corporation complied with the Occupational Safety and Health Administrations Standard for Vinyl Chloride. Discontinued the manufacture of vinyl chloride copolymer fiber and dispersion vinyl resins at South Charleston, West Virginia. Discontinued the manufacture of suspension and bulk process vinyl chloride resins at Texas City, Texas. Union Carbide Corporation through Chemical Kanufacturers Association co-spcnsored an epidemiological study of workers in the vinyl chloride-polyvinyl chloride industry. Study in progress. Discontinued the manufacture of solution polymerized vinyl chloride resins at South Charleston, W. Va. ucc 059708
