Abstract
Disclosed is a hot-melt adhesive composition comprised of an admixture of a polyetherester, polystyrene and optionally a filler. The adhesive composition exhibits a desirable overall balance of properties, including good bond strength, particularly after aging. In a preferred embodiment, the adhesive composition can be used to bond poly(vinyl chloride) to wood or particleboard.
Claims3
A composition comprising, based on the weight of the composition, an admixture of
- A. from 95-60 weight percent of a polyetherester having an inherent viscosity in the range of 0.5 to 1.4, the polyetherester being comprised of
