Abstract
The invention relates to a process for the treatment of substantially amorphous polyolefin/hydrocarbon rubber blends with peroxides at high temperatures to provide permanently tacky, low viscosity materials which have useful pressure-sensitive adhesive properties. These permanently tacky blends are obtained, for example, by treating a blend of substantially amorphous polyolefins, such as amorphous polypropylene or amorphous propylene/1-butene copolymers, and a hydrocarbon rubber, with peroxides at high temperatures.
