| titleOfInvention | Polyether-ester block copolymer and filaments formed therefrom |
| abstract | A polyether-ester block copolymer, and filaments formed therefrom, having an enhanced thermal stability of the elastic property thereof and a satisfactory dyeing property, comprises a polymerization product of (A) an acid component comprising as a major ingredient, terephthalic acid, (B) a phosphonium sulfate component comprising a compound of the formula (I):n wherein Z 1 = tri- or more valent aromatic or aliphatic group, A 1 = ester-forming group, A 2 = H or ester-forming group, R 1 , R 2 , R 3 , R 4 = alkyl or aryl radical and n = a positive integer, (C) a polymeric glycol component comprising a polyoxyalkylene glycol having an MW of 400 to 6000 and (D) a monomeric glycol component comprising, as a major ingredient, 1,4-butane diol, in which copolymer the component (B) is in an amount of from 0.1 to 5 molar% based on the molar amount of the component (A) and the component (C) is in an amount of from 50 to 80% by weight based on the total weight of the copolymer, and which copolymer has a limiting viscosity number of 1.2 or more, a melting point of 160°C or more, and a 1/2 crystallization time of 10 seconds or less. |
