Abstract
The invention relates to a process for the treatment of substantially amorphous polyolefins to provide permanently tacky, low viscosity materials which have useful pressure-sensitive adhesive properties. These permanently tacky amorphous polyolefin homo- and copolymers, as well as blends of such amorphous polyolefins with crystalline polyolefins containing up to 20 weight percent crystalline polyolefin, are novel pressure-sensitive adhesives.
