Gordon - St. Louis To improve biodegradability some experimental Aroclor 1242 with some of the higher chlorinated biphenyls removed is being prepared. This material has already been called Aroclor 1242B. Obviously the "B" implies biodegradability. Me now feel that this nomenclature is not desirable at this stage of this new and not fully explored material. _______ _ Therefore, we now elect to call this material MCS \oi^l). Please now use this designation, instead of Aroclor xg^B^V^ Thank you. /dn Paul G. Benignus OSNN WO262 STLCOPCB4058326
