摘要： PURPOSE: To prepare the titled composition having pill resistance, etc. and excellent thicknening effect, and suitable as fiber, etc. without causing the decomposition, discoloration, etc. of the polyester or the lowering of the moldability, by adding a specific silicate compound to a polyester.
CONSTITUTION: A saturated polyeser, esp. crystalline polyester wherein ≥70mol% of the structural unit is ethylene terephthalate is compounded with ≥0.1wt%, esp. ≥0.3wt% silicate compound of formula M
2 O.nSiO
2 (M is NH
3 , Li, Na, or K; n is 2W20 when M is NH
3 or Li, and n is 5W20 when M is Na or K). The addition of the silicate compound is esp. pref. carried out by adding the silicate in the form of aqueous solution or aqueous colloid during the esterification reaction, and cointinuing the reaction to complete the polycondensation reaction.
