2. Synthesis of statistical networks from liquid telechelic dimethylhydrogenosilane polydiene

Abstract

A new route to the synthesis of statistical networks similar to vulcanized rubber, from 1,2-polybutadiene (PBD) and 3,4-polyisoprene (PI) is described. The two antagonist chemical functions are both present on the polydiene backbone. The latter could be used as precursor polymer and as difunctional crosslinker simultaneously; the reactive groups are respectively the dimethylhydrogenosilane end groups and the pendent double bonds along the polydiene backbone.
