Abstract
PURPOSE: To prepare a hydrophilic polyester, of good processing characteristics in spinning, by compounding a polyester with a specified polyoxyalkyleneglycol (functional derivative).
CONSTITUTION: (A) A polyester, in which at least 80mol% of its repeating unit is composed of ethylene-terephthalate, is compounded with 0.5W90wt% a polyoxyalkyleneglycol or its functional derivative of number-average MW 4,000W 200,000, having Hazen unit (APHA standard method) of ≤500, in molten state, after treatment at 280°C, for 2hr, in nitrogen atmosphere (e.g.; polyethylene glycol, random copolymer of ethylene oxide and propylene oxide).
