Abstract

1289365 Optical brighteners FARBENFABRIKEN BAYER AG 6 April 1970 [5 April 1969] 16224/70 Heading C3R [Also in Divisions C2 C4 C5 and D1] In Example 12, polyethylene terephthalate has incorporated therein one of the brighteners listed below. The brighteners are added to the starting materials (terephthalic acid dimethyl ester and ethylene glycol) before the transesterification step; and the product after the polycondensation step is subsequently spun to give filaments. The brighteners are of general formula where, if R = CH 3 then X = CN, or if R = H, X is one of
