Patent ID: 7629430

Claim:
A hybrid silane composition comprising a mixture of compounds corresponding to the general formula: F 1 r F 2 s Formula (I) wherein r is 0 to 10,000; s is 0 to 10,000; with the proviso that r has a value of 1 to 2 and s has a value of 1 to 3 for at least one compound of Formula (I) in the mixture of compounds; F 1 is a sulfur silane structure selected from the group consisting of: {(R 1 O) 3-m-n [(—O—) 0.5 ] m R 2 n Si-G 1 -S x —(C=E) y -E z } p -G 2 Formula (II) and {(R 1 O) 3-m-n [(—O—) 0.5 ] m R 2 n Si-G 1 -S x —} 2 (C=E) y Formula (III) wherein each occurrence of R 1 and R 2 is independently hydrogen, or any group which can be obtained by removal of one hydrogen atom from a hydrocarbon group having from 1 to 20 carbon atoms, including branched or straight chain alkyl, alkenyl, aryl or aralkyl groups; each occurrence of G 1 is any group which can be obtained by removal of a quantity of two hydrogen atoms from any hydrocarbon having from 1 to 20 carbon atoms; each occurrence of G 2 is independently a hydrogen atom or any group which can be obtained by removal of a quantity of p hydrogen atoms from any hydrocarbon having from 1 to 20 carbon atoms; S is sulfur; O is oxygen; Si is silicon; each occurrence of E is independently oxygen or S x ; each occurrence of m can be 1 or 2 and n can be 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 2 is a nonsulfur silane structure represented by the general formula: (R 1 O) 4-m′-n′ [(—O—) 0.5 ] m′ R 3 n′ Si Formula (IV) wherein each occurrence of R 1 is as defined above; each occurrence of R 3 is independently hydrogen, or a hydrocarbon group of 1 to 20 carbon atoms including aryl as well as branched or straight chain alkyl, alkenyl, arenyl, or aralkyl groups; and each occurrence of m′ can be 1, 2 or 3 and n′ can be 0, 1, 2 or 3.
