Title:
PREPARATION OF AQUEOUS DISPERSION OF POLYESTER AND EASILY BONDABLE POLYESTER FILM COATED THEREWITH
Document Type and Number:
Japanese Patent JPS60248231
Kind Code:
A
Abstract:

PURPOSE: To obtain aq. dispersion of fine polymer particles having improved dispersion stability by dispersing uniformly a substantially water-insoluble polyester copolymer having 0.2W0.8 intrinsic viscosity and a specified compsn. in water contg. no org. solvent.

CONSTITUTION: A copolymerized polyester having 0.2W0.8 intrinsic viscosity and being substantially insoluble in water is synthesized from an acid component consisting essentially of ≥40mol% terephthalic acid and 0.5W5mol% arom. dicarboxylic acid contg. metallic salt residue of sulfonic acid, and a glycol component consisting essentially of ethylene glycol and 15W60mol% neopentyl glycol. The copolymerized polyester is dispersed uniformly in water contg. no org. solvent to obtain an aq. dispersion of polyester.
