Abstract: A process for preparing an organosilane composition includes reacting a) an organosilane and b) a polyoxyalkylene in the presence of c) a hydrosilylation catalyst. The organosilane a) is of the formula: (R1)(3-n)(R2O)nSiH. R1 is a hydrocarbon group containing 1 to 12 carbon atoms, R2 is hydrogen or an alkyl group containing 1 to 6 carbon atoms, and “n” is 1, 2 or 3. The polyoxyalkylene b) is of the formula: R5O(CH2CH2O)a(C3H6O)bR4. In this formula, a?0 and b?0 with the proviso (a+b)?1. R4 is hydrogen, R1, or an acetyl group. R5 is a hydrocarbon group including a terminal allylic unsaturated group. A composition comprising an organosilane is also disclosed. The organosilane is of the formula: (R1)(3-n)(R2O)nSiR3O(CH2CH2O)a(C3H6O)bR4. Each of “n”, “a”, “b”, R1, R2 and R4 is as defined above. R3 is a divalent hydrocarbon group containing 2 to 12 carbon atoms.

Abstract: The present disclosure relates to compositions comprising an organosilane having the formula; (R1)n(R2O) (3.n)SiR3O(CH2CH2O)a(C3H6O)b R4 where n is 1 or 2, a?1, b may vary from 0 to 30, with the proviso a?b, R1 is a hydrocarbon group containing 1 to 12 carbon atoms, R2 is hydrogen or an alkyl group containing 1 to 6 carbon atoms, R3 is a divalent hydrocarbon group containing 2 to 12 carbon atoms, R4 is hydrogen, R1, or an acetyl group. The present organosilane compositions are particularly useful to treat various surfaces to render them more hydrophilic.
