Patent ID: 8431232

Claim:
A hot-melt adhesive composition, comprising: A. about 50 to 100 weight percent, based on the total weight of said adhesive composition, of at least one polyester, comprising (i) diacid residues, comprising about 30 to 60 mole percent, based on the total moles of diacid residues, of the residues of adipic acid, glutaric acid, or a combination thereof, about 30 to about 60 mole percent of the residues of terephthalic acid, and about 0 to about 40 mole percent of at least one modifying dicarboxylic acid having about 4 to about 40 carbon atoms; and (ii) diol residues, comprising about 90 to about 100 mole percent, based on the total moles of diol residues, of the residues of 1,4-butanediol, and about 0 to about 10 mole percent of the residues of at least one modifying diol; and B. 0 to about 50 weight percent of a tackifier, plasticizer, wax, nucleator, or combination thereof; wherein said polyester has an inherent viscosity of about 0.1 to about 0.35 dL/g as measured at 25° C. using 0.5 grams of polymer per 100 ml of a solvent comprising 60 weight percent phenol and 40 weight % tetrachloroethane, a melting temperature of about 70 to about 130° C., and a heat of melting of about 0.1 cal/g to about 6 cal/g, and wherein said adhesive composition has a melt viscosity of about 300 to about 3000 centipoise at 150° C.
