Zusammenfassung: | Copolyesters useful as melt adhesives in the bonding of fabrics, metal, glass, wood, rubber, plastic sheets and other products to produce a bond which will resist the action of heat, steam, dry cleaning solvents and the like, said copolyester being derived from (1) terephthalic acid, (2) adipic acid, (3) ethylene glycol, and (4) 1,4-butanediol or derivatives of these four components. These copolyesters are advantageously improved by the incorporation therein of specific amounts of either sodium stearate or titanium dioxide. |
