Abstract
An stable ethylsilicate polymer having a dynamic viscosity of 10 centipoises (cps) to 1,000 cps at 25° C. and 50 wt % to 60 wt % silica (SiO). The stable ethylsilicate polymer includes not greater than 1 wt % of TEOS monomer. The process of forming the ethylsilicate polymer includes a two step addition of catalysts. A hydrolysis catalyst is added initially, for example hydrochloric acid, and a second catalyst is added subsequently, such as phosphonitrilic chloride trimer. The ethylsilicate polymer is used to form MQ resins.
