GENERAAU1tD OW-"u w C'-.viSioN f l*1' 0 i ? v'V '/ November 7, 1962 Mr. John Frangos Revlon Corporation 2417 Third Avenue Bronx, Nex^ York Dear Jolm: Please forgive the delay in answering your telephone questions. On toxicity of vinyl chloride, enclosed is my only copy of Lester et al paper which was submitted for publication. Even this copy is not too good because it was made from Dave Lester's carbon copy. I will appreciate it if you will return this as soon as conven ient. Will get reprints for you when it is published. The results here disagree with Torkelson, et al., AM.IND., HYG. ASSOC. J., October 1961, pg. 354, but we believe we are right and MC for vinyl chloride will probably remain at 500 ppm at least for the time being. On hydrolysis, can find no data in our files but have contacted Solvay Technical Service who think they have some data. If and when X get it will forward to you. The only thing they have said in their reports is that vinyl chloride is not decomposed by boiling 207. caustic. Accordingly, am inclined to believe that hydrolysis may be lox/ even as compared to Genetrons. Very truly yours, WAR:dmk Enel. !?' i B f -7'v W. A. Knapp Research Consultant ASl 00001 37s 7
