Disclosed are low-melting blends of polyesters and polyethylene glycols which are useful as adhesives.
Claims11
A composition comprising a blend of
- (a) about 75-99% based on the total weight of the composition of a polyester having a melting point of about 80.degree. C.-180.degree. C., a heat of fusion of about 1-10 calories per gram and an I.V. of about 0.4-1.2, and
- (b) about 1-25% based on the total weight of the composition of a polyethylene glycol having a melting point of about -15.degree. to about 67.degree. C. of the formula ##STR2## wherein n is an integer which provides a molecular weight of about 200-14,000.
