ABSTRACT:
Polyesters useful as hot melt adhesives are prepared from selected dicarboxylic acids and selected diols, which include a critical range of polyoxyethylene glycols. In a first embodiment of the invention, the polyester is prepared from terephthalic acid, isophthalic acid, adipic acid, 1,4-butanediol, ethylene glycol, and 20 to 45 weight percent of the selected polyoxyethylene glycols. In a second embodiment of the invention, the polyester is prepared from terephthalic acid, acipic acid, 1,6-hexanediol, ethylene glycol, and 2 to 40 weight percent of the selected polyoxyethylene glycols.
