NEW POLYMERS OF THE CATALYTIC POLYMERIZATION OF ORGANOSILOXANES
Abstract
A study has been made of the process of catalytic polymerization of cyclic products containing phenyl-, phenylmethyl-siloxane groups, and phenyl-, phenylmethyl-, and dimethylsiloxane groups at 120 degrees, an ethylsulfuric acid as a catalyzer. It was established that in the cohydrolysis of phenyltrichlorsilane with phenylmethyldichlorsilane, or the same products with dimethyldichlorsilane, cycles are formed which polymerize partially under the effect of an acid catalyzer at high temperatures. During the process of polymerization, a partial breaking off of the phenyl groups takes place simultaneously, accompanied by the formation of polymers of branched structure and low molecular weight.
