摘要：
The present invention provides for a composition comprising a silane having the formula: (R1)(R2)(R3)Si—R4—Si(R5)(R6)(R7) wherein R1, R2, R3, R5, and R6 are each independently selected from the group consisting of 1 to 6 monovalent hydrocarbon radicals, aryl, and a hydrocarbon group of 7 to 10 carbons containing an aryl group; R4 is a hydrocarbon group of 1 to 3 carbons; R7 comprises an anionic, cationic or zwitterionic substituent. The silanes of the present invention exhibit resistance to hydrolysis over a wide pH range.
