Abstract:
1. A process of making a hybrid silane composition comprising the steps of hydrolyzing a sulfur silane and a nonsulfur silane in the presence of a hydrated alkali metal salt to effect partial hydrolysis of silane alkoxy groups on each of the sulfur silane and nonsulfur silane, and bonding the partially hydrolyzed sulfur silane and nonsulfur silane to each other via Si—O—Si linkages, said hybrid silane composition comprising a mixture of compounds corresponding to the general formula: wherein r is 0 to 10,000; s is 0 to 10,000; with the proviso that r and s each have a value of at least 1 for at least one compound of Formula (I) in the mixture of compounds; F  and  wherein each occurrence of R each occurrence of G each occurrence of G S is sulfur; O is oxygen; Si is silicon; each occurrence of E is independently oxygen or S each occurrence of m and n is independently 0, 1 or 2; each occurrence of p is independently 1 to 4; each occurrence of y is 1 and z is independently 0 or 1; and each occurrence of x is independently 1 to 8; F  wherein each occurrence of R each occurrence of R each occurrence of m′ and n′ can be independently 0,1, 2 or 3.
