Abstract

A method for making silarylene-siloxane polymers having the Formula: ##STR1## where R.sub.1 -R.sub.6 are alkyl or aryl and n is an integer above about , wherein the rate of reaction and the degree of polymerization achieved when reacting disilanols with dichlorosilanes to form silarylene-siloxane polymers are unexpectedly enhanced by a subsequent charge into the reaction medium of a tertiary amine which functions as an acid acceptor.
