St. Paul, Minnesota ` The "O" resin seminar was presented to the Industr and Retail Tape and Electrical Products Divisions of 3M. The reception was generaU^ favorable and interest was forth coming for use of these resins In both rigitf a flexible applications. Appropriate samples are being submitted. A strong feeling is evident at this customer that all resins purchased must be of our "double-washed" variety.

Both resin and plasticizer business are at stake. From the physical properties required, a plasticizer system was deter mined by computer (28 seconds elapsed time ) and the ultimate resin choice, QYTQ/QYSJ, made on the basis of apparent melt viscosity.
