Abstract
Abstract Disclosed are linear, crystalline or partially crystalline copolyesters derived from 100 mole % of a dibasic acid component comprising at least 40 mole % terephthalic acid and up to about 60 mole % of a second dicarboxylic containing 3-12 carbon atoms, and 100 mole % of a glycol component comprising at least 40 mole % 1,4-butanediol and up to about 60 mole % diethylene glycol, the copolyester characterized by having a melting point of about 40°-220° C., a glass transition temperature of about -20° C. to about 40° C., a heat of fusion of not less than 1.0 calorie per gram, and a crystalline half time of less than 10 minutes at maximum crystallization temperature. These copolyesters are especially useful as fusible interlining adhesives and binder fibers.
