Abstract
Adhesive compositions based on chlorinated polyolefins having chlorine contents greater than about 60 percent and molecular weights greater than about 500. The adhesive compositions contain the chlorinated polyolefin and a phenolic resin. The chlorinated polyolefins are advantageous in that they can be prepared in an environmentally acceptable manner and can be utilized as a substitute for the traditional chlorinated natural rubber materials utilized in adhesive compositions without compromising adhesive performance. Preferred chlorinated polyolefins are prepared by a process involving the dispersion and chlorination of high surface area polyolefinic particles in an aqueous medium.
