Abstract
Disclosed are heat-resistant adhesive compositions comprising a copolyester derived from terephthalic acid, from about 30 to about 50 mol % diethylene glycol, and at least 50 mol % ethylene glycol, the polyester having an inherent viscosity of from about 0.4 to about 1.0. The composition is especially useful in bonding parts of ovenable food containers.
