  • Method of using siloxane polymers
    Patent number: 5853808
    Abstract: Silsesquioxane polymers that are useful for preparing SiO.sub.2 -rich ceramic coatings are obtained as the polymeric reaction products from the hydrolysis and condensation of organosilanes having a .beta.-substituted alkyl group. A preferred silsesquioxane polymer is the polymeric reaction product obtained from .beta.-chloroethyltrichlorosilane. Coating compositions containing such silsesquioxane polymers dissolved in organic solvent may be applied to a substrate and converted to SiO.sub.2 -rich ceramic thin layers by evaporating the solvent and heating the coated substrate at moderate temperatures.
