Polymeric compd. (I; R1, R2 = aryl, arylalkyl, C1-3 alkyl; n' = 1-3; n = 10-50; m = 0-2) 55-30 wt. % (preferably, 10-20%) was added to polymn. or spinning process of polyethylenetere-phthalate fiber. For exampl, the extent of burning, time of burning and L value of whiteness of the polyesterfiber (contg. 10 wt. % poly dibromo bis hydroxyethylene terephthalic cresyl phosphoric ester) was 4.2 cm, O sec and 82, resp.
