Abstract

Crystalline co-polybenzyls are prepared by the polymerization of 2,5-dimethylbenzyl chloride with a benzyl halide of the same series. The polymers have utility in general thermoplastic applications such as, for example, the manufacture of conduits, hoses and pipes, as coatings for wire and cables, the manufacture of seals, molds and mechanical goods, tanks and pipelinings, and in other articles of manufacture.
