Claim:
A halo-functional silane possessing halogen functionality and alkanedioxysilyl functionality, and partial hydrolyzates thereof, selected from one of general Formulae (1) and (2): Y 1 (—SiZ θ X 1 ) a (1), and [Y 1 (—SiZ θ Z β ) a ] m [Y 1 (—SiZ β 3 ) a ] n (Y 1 (—SiZ β 2 X 1 ) a ] o [[Y 1 (—SiZ β X 1 2 ) a ] p (2) wherein: each occurrence of Y 1 is a monovalent or polyvalent halo-containing hydrocarbon group of up to 30 carbon atoms of general Formula (3): [(Z e CR 3-e ) b Y 2 ] c G 1 d (3) wherein each occurrence of G 1 is independently a divalent group selected from the group consisting of —(CH 2 ) j —, where j is an integer from 18, —CH 2 (CH 2 ) i CH(CH 3 )—, where i is an integer of from 0 to 15, and —CH 2 CH(CH 3 )CH 2 —; each occurrence of Y 2 is independently an unsaturated group selected from the group consisting of —CH═CH—, phenylene and 2-methyl phenylene; each occurrence of Z is independently a Cl—, each occurrence of R is hydrogen; each occurrence of X 1 is independently selected from the group consisting of a methyl, ethyl, propyl, isopropyl, sec-butyl, phenyl, methoxy, ethoxy, propoxy, isopropoxy, butoxy, phenoxy, benzyloxy, and hydroxyl; each occurrence of Z β , which forms a bridging structure between two different silicon atoms, is [—OG 2 (OH) f-2 O—] 0.5 , wherein each occurrence of G 2 is independently selected from the group consisting of a hydrocarbylene group of from 2 to 15 carbon atoms or a divalent heterocarbylene group of from 4 to 15 carbon atoms containing one or more etheric oxygen atoms; each occurrence of Z θ , which forms a cyclic structure with a silicon atom, is —OG 2 (OH) f-2 O—, wherein G 2 is independently selected from the group consisting of a hydrocarbylene group of from 2 to 15 carbon atoms or a divalent heterocarbylene group of from 4 to 15 carbon atoms containing one or more etheric oxygen atoms; and, each occurrence of subscripts a, b, c, d, e, f, m, n, o and p is independently an integer where a is 1; b is 1; c is 1, d is 0 or 1; e is 1; f is 2 to 6; m is 0 to 20; n is 0 to 18; o is 0 to 20; and, p is 0 to 20, with the proviso that m+n+o+p is equal to or greater than 2.
