Synopsis
Excerpt from Standard Reference Materials: Comparison of Original and Supplemental Srm 705, Narrow Molecular Weight Distribution Polystyrene
Early in 1963 the National Bureau of Standards issued its first polymer Standard Reference Material, sbm 705 [l], a narrow molecular weight distribution polystyrene. Recently the original supply of one of these, srm 705, became very low, but additional material, which had previously been sent to the Bureau by Dow Chemical Company, was available. According to the letter by Dr. H. W. Mccormick of Dow Chemical Company, Midland, Michigan, dated September 7, 1966, to Dr. Emanuel Horowitz, this additional supply is the same as the original. Because this is a certified material, however, it was nec essary to compare the original and the new material to make certain that the two are indistinguishable as far as the properties listed on the certificate are concerned. About 4900 grams of this second sample are available and will be referred to as srm 7osa in this report only.
