FROM (NAME ft LOCATION) W. F. Wayohoff - St. Louis General Offices DATE SUBJECT REFERENCE TO November 11, 1968 PLASTICIZER AROCLOR FROM BIPHENYL FROM BXT OPERATIONS CC: J. S. Bagnall - JBA.GN D. L. Chapman - DCHAP W. K. Johnson - WJOHN A. L. Klemm - AKLEM D. A. Olson - DOLSO C. Paton W. R. Richard - WRICH W. E. Schalk - WSCHA In your memo you asked whether or not Aroclor 1242 based on biphenyl as a byproduct of BXT operations would be satisfactory for NCR's application. Answer - we do not know. J3y~eopy of this memo, I am requesting C. Paton to contact Bill Kuhn to determine what wdrF~was dons, and if samples remain. The only way to determine if"satisfactory is to sample NCR. This we could do in a disguised manner. We are currently selling Aroclor 5060 and Aroclor 5^-60 to Sun Chemical. Sales year to date are as follows: Aroclor 5060 44.000 pounds Aroclor ^k-60 88.000 pounds Koppers' production of Aroclor 5060 and 5460 competitors were based on Dow taraphen D-25. This is a terphenyl stream, not biphenyl. To the best of our knowledge, Koppers has never made chlorinated biphenyls, only terphenyls. WFW/cs W. F. WAYCHOFF IN- IO REV.
