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 (Si02). 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.

2 and having viscosity of 50 cps at 25° C. to about 750 cps at 25° C. and which is essential free of monomer is disclosed. The stable resin solution is made by a two step addition of catalysts wherein a hydrolysis catalysts, as for example, hydrochloric acid is added initially and a second catalysts such as Phosphonitrilic chloride trimer is added subsequently.
A stable suspension of ethylpolysilicate nanoparticles having a size of between about 5 nm and 120 nm are in water and stabilized with between about 0.05 and 5 weight percent tetraalkylammonium hydroxide. The particles are between about 95% and 99.5% hydrolyzed and have superior removal rates when used in chemical mechanical polishing. A process for making ethylpolysilicate nanoparticles includes the step of adding reverse osmosis water and 25% tetramethylammonium hydroxide and ammonium hydroxide to a reactor, agitating the mixture and heating the mixture to about 80° C. Tetraethylalkoxy silane is added to the mixture and the mixture stirred and hydrolyzed. Ethanol is then removed. The mixture was then subjected to a vacuum to remove additional distillate. The material left in the reactor was then transferred to a plastic drum.
