1. A novel process for the production of a polymeric substance from silicon alkoxide comprising in order the steps of:
- (a) mixing an alcohol and silicon alkoxide in the presence of an esterification catalyst;
(b) adding to said mixture in 1(a) a carboxylic acid in order to form a polymeric network of silicon alkoxide; and
(c) adding calcium acetate to said polymeric network of silicon alkoxide formed in 1(b) in an amount of from about 0.1-2 wt % of the weight of said polymeric network of silicon alkoxide solution.

Abstract
Polymeric silicon alkoxide solutions are produced and then stabilized by the addition of calcium acetate. The calcium acetate serves to prevent the rapid evaporation of the polymerized silicon solution when applied as a coating to various substrates. Glass fiber substrates are preferred.
