Abstract

A linear saturated crystalline polyester of an acid moiety and a moiety of a dihydric alcohol, at least 40% of the acid moiety being a terephthalic acid moiety, said polyester containing moieties of 1,4-butanediol and 1,6-hexanediol, the ratio of the 1,4-butanediol moieties to 1,6-hexanediol moieties being 10:90 to 90:10; the use of such polyesters as a fusion coating mass, particularly in securing textile substances to a substrate.
