ABSTRACT:
Hydrosoluble/hydrodispersible polyester copolycondensates, well suited for the sizing of textile threads, comprise terephthalate, isophthalate, sulfoaryl dicarboxylate, ethylene glycol and polyoxyethylene glycol recurring structural units, have a glass transition temperature ranging from 15.degree. to 40.degree. C. at 85% relative humidity and the turbidity of aqueous formulations thereof are storage-stable over time; such polyester copolycondensates are conveniently prepared by (i) transesterifying admixture of dimethyl terephthalate, dimethyl sulfoaryl dicarboxylate and ethylene glycol, (ii) introducing isophthalic acid and an additional amount of ethylene glycol into the medium of transesterification and therein directly esterifying same, and (iii) polycondensing the resulting product of transesterification/direct esterification.
