摘要： 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 crosslinking agent. 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 are apolyolefinic particles in an aqueous medium.

摘要： 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.
