However, the road to large-scale production was not opened until vinyl chloride coulJ he synthesized from acetylene and hydrogen chloride (Klatte and Zacharias. 1912)' " and or ganic peroxides were used for catalyzing VC polymerization (Klatte and Rolled, 19I4).*1 In 1928. PVC production was started in the United States and in I93J in Germany." The enormous growth of VC anil I'VC production capacities over ihs past 45 years ran parallel to the rising economic importance of plastic materials" (Taiu.i: 1). PVC-producing industries in West Germany increased their production, parallel to the development in the United States (Ta,u l 2l. at a rate of 10-20 percent per year from 1960 (172,673 tons of PVC) to 1972 (930,701 tons of pVC and poiyvinylidenc chloride).''" Total sales of PVC amounted to 850.140 German marks in J 972."' This enormous increase in production capacity, espe cially in flexible PVC (U.S.. 1965: flexible PVC, 90 percent: rigid PVC, 10 per cent)* can be explained by the almost unlimited use that can he made of PVC Diversification of PVC markets exceeds-ih.il of any other large-volume thermo plastic and is one of the reasons for the increasingly favorable market situation (Tasi-e 3).`" Rigid PVC is-used for tubing and linings (including insulation material and drainage pipes), foils, films, and sheeting (packaging, lining, recording tapes), profiles (blinds, window frames), tiles, sounj records, and fibers. Flexible PVC jj used for cables, foils fdceoration. roof covering), profiles, tubing, artificial feather, flooring, foam rubber, paint, varnish (lacquer). and toys."' Thus, indus tries that manufacture the end product operate on a much larger scale than those producing the polymer, but the companies arc often identical.'*'11 Technologically, vinyl chloride was synthesized mainly by hydrochlorination of acetylene, a process which was almost exclusively in operation up to 1960. fcal in the Uniled States now accounts for only 7 percent of the production." Vinyl chloride can also be prnlueed by oxychlorination of ethylene to 1,2-di- chlorocthane which is then cracked to VC anil HCI by subsequent pyrolysis (now 93 percent of total production in the United States in 1972).'

Grrm.iry); It would seem better for statistical investigations on the reported liver function tests if von could compare the results with similar tests done before the workers came into vinjl chloride manufacturing. Second, in one of the two plants in Germany with incidence of vinyl chloride disease, there is much alcohol intake in the workers- Until now no liver damage has beer, found. Third, in regard lo low lung-function tests, we have not confirmed a pathological diagnosis al all. There should be more discussion about (he cause of this disease, i.c.. whether it is vinyl chloride alone or another agent which may get together with technicJ vinyl chloride, or vinyl aceratc or additives. This may be important in the causation of angiosarcoma. Last, i! has been suggested that liver biopsy be done only after peritoneoscopy because of the risk of bleeding. Dr. M. L. Nfwhouse: May I ask Dr. lelbach how he selected his patients and boss big was tlic exposed group he selected them from? Dr. W. K. Lf.lb.acii (University oj Bonn. Germany): 1 will begin with thr answer to the second part of the question. The whole group is, as far as we know, about 1R0 workers in this plant. We were alerted in December 1972 by Dr. Vcltman's group that patients being examined for skin and bone disease also had signs of liver disease. We examined these patients. l ater wc examined all patients we could bring to the clinic. It is. of course, selected group and docs not permit us to draw conclusions as to percentages. B.
