摘要: A method for purifying alkoxysilane with the general formula, R.sub.m Si(OR.sup.1).sub.4-m. The method significantly lowers the level of non-hydrolyzable chlorine-based impurities, as well as the level of hydrolyzable chlorine-based impurities. The method comprises: (i) heating the alkoxysilane in the presence of a treating agent selected from a group which consists of acid clays and metal halides; (ii) contacting the alkoxysilane with a neutralization agent; and (iii) separating the alkoxysilane from the unused neutralization agent and by-products of neutralization.

摘要: The silicone rubber obtained by curing in the presence of a platinum-containing catalyst a composition comprising an organopolysiloxane containing a plurality of lower alkenyl radicals and a organohydrogensiloxane consisting essentially of R.sub.3 SiO.sub.1/2 units, R.sub.2 SiO units, RHSiO units, and RSiO.sub.3/2 units in a specified molar ratio is uniquely suitable as the coating material for the press roll in the fixing assembly of an electrophotographic copier.
