Overcoat and Adhesive Compositions Based on Chlorinated Polyolefins Having High Chlorine Contents

摘要

Adhesive compositions based on chlorinated polyolefins having chlorine conte nts greater than about 60 percent and molecular weights greater than about 500. The adhesive compositions contain the chlorinated po lyolefin and a crosslinking agent. The chlorinated polyo lefins are advantageous in that they cam be prepared in an environmentally acceptab le manner and can be utilized as a substitute for the tr aditional chlorinated natural rubber materials utilized in adhesive compositions witho ut compromising adhesive performance. Preferred chlorina ted polyolefins are prepared by a process involving the dispersion and chlorinat ion of high surface are apolyolefinic particles in an aq ueous medium.
