Abstract

1,240,116. Elastomeric filaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. 29 May, 1969 [7 June, 1968], No. 27264/68. Heading C3R. Elastomeric filaments having an elastic recovery from 100% extension of at least 95% and a work recovery of at least 75 % after annealing are formed from a polyetherurethane having an inherent viscosity of 0.5 to 1.5 obtained by the interaction of (1) a diol which is a hydroxylterminated linear polyether or copolyether having a number average molecular weight of 1000 to 6000, (2) from 0À1 to 20 mole, per mole of (1), of an aliphatic, cycloaliphatic or arylaliphatic diol and (3) from 96 to 106 moles per 100 moles total of the aforesaid diols of paraxylylene diisocyanate or trans,trans,4,4<SP>1</SP>-diisocyanato-dicyclohexylmethane. Catalysts may be added to the reaction mixture and the reaction may be carried out in solution. In a typical example a hydroxy-terminated poly- (tetramethylene oxide) glycol is mixed with 4,4<SP>1</SP>- diisooyanato - dicyclohexylmethane (transtrans isomer) and after heating and cooling pbis - (# - hydroxyethoxy)-benzene is added. The resulting polyurethane is melt spun into a filament yarn.
