The^aCare based on recommendations made by Messrs. Wheeler, Bush, Mcey, and Zutty. Your attention is directed to the following points: (a) In anticipation of early approval, this product is Identified as QSOM-7^/ It should be noted though that it was agreed earliev'-'that the designation 7 would be used only for FDA ,2*4* approved products. We are advised by Dr. Ackart that, although FDA approval is (excepted, it has not yet been obtained. (b) It is agreed that ethylene content must be defined sooner or later and the limits proposed are those recommended by Texas City. However, it also has been suggested that ethylen content remain on a DAR basis until more experience has been acquired. Dr. Zutty objects to this. A decision Wh that . . point is requested. 7 t (c) It is Dr. Zutty's opinion that aAOy range for inherent Up viscosity is too broad to maintaltfthe desired melt viscosity. I </<*/> He recommends that this range certainly not exceed .03 and preferably be kept within .02 if possible. If * /yv isiJ <fd Is** M^d UJ M , tsrJ VfC. rvSWf* fr*r**f*''Z d ~tr ^ if 3 .

Early replies are requested since ve understand that marketing of this resin in the near future is planned. DB:jal D. Barbieri ucc 039503 UCC.

It leads to lower melt viscosity in rigid or non-rigid compounds, and hence faster production or output rates of finished products. QSOM-7 has excellent initial color and ultimate stability, is commercially free of fish-eyes, and has very good dry-blending characteristics. It meets the requirements of ASTM Specification D1755 for Type GP-4-1534.

Methods of the American Society for Testing Materials are identified by the prefix letter "D". Standard Testing Methods of Union Carbide Plastics Division are identified by the prefix letters "WC". Details of the "WC" - methods are available on request. PACKAGING The standard package for BAKELITE Vinyl fabricating resins is a four-ply multiwall Kraft paper bag containing 50 pounds of material. If desired these resins also can be supplied in hopper cars containing a minimum of 100,000 pounds. LABELING All containers of BAKELITE Vinyl fabricating resins are plainly marked with the product number, lot number, and net weight. Shipments will b so addressed as to assure complete delivery to the purchaser.
