Abstract
Polyester urethanes containing the repeating unit (a) of formula <FORM:1019114/C3/1> together with, or in the absence of, the repeating unit (b) of formula <FORM:1019114/C3/2> the units (a) and (b) being arranged in random order and the ratio of the number of units (a) to (b) when present being from 2:1 to 19:1, where R = arylene, R1 is the residue of an aliphatic or aromatic disecondary diamine or a sterically hindered aromatic diamine, R11 = divalent atomatic or aliphatic radical, x = an integer from 2 to 10 y = an integer from 1 to 5, may be prepared by reacting an hydroxyl terminated polyester e.g. a bis (o -hydroxalkyl) dicarboxylate with a diisocyanate. A diamine may be added to the reaction mixture and the reaction may be effected in an organic solvent. In Example (1) hexamethylene diisocyanate was reacted with bis (b -hydroxyethyl) terephthalate and in Example (4) piperazine in dimethyl formamide was added. The solutions were spun to form filaments.
