<p>An organosiloxane cpd. has the formula XmR2(3-m)SiOR1(Si(R3)3)n (I) where R1 contains at least 3C, has a valence of n+1 and is selected from -R4;, -R4OR5-, -R4OC(O)R6-, -R7C(O)OR5- when n = 1 and from (-R4O)2R8- when n = 2; R5, R6, R8 are bonded to the oxygen in the formula; R4, R6 = hydrocarbylene radical contg. at least 3C opt. substd. by hydroxyl or alkoxy; R5 = 2-12C hydrocarbylene or alkoxy-substd. hydrocarbylene radical; R7 = as R6 or a single bond; R8 = trivalent hydrocarbon radical; R2 = opt. substd. monovalent hydrocarbon radical; R3 = opt. monovalent hydrocarbon radical, silicon bonded H atom, X or siloxane units of formula -O(SiR9pO(3-p)/2)q (II), q = at least 1, the siloxane units being sequential when q is greater than 1; R9 = X, H, opt. substd. monovalent hydrocarbon radicals, XmR23-mSiOR1- (III) or -R11(R10sSiO(3-s)/2)r (IV); r = at least 1 and the siloxane units (R10sSiO(3-s)/2)r are sequential when r is greater than 1; with the proviso that at least one substit. R3 contains a Si-bonded H atom or alkenyl radical; R10 = monovalent hydrocarbon radical, H or X; R11 = hydrocarbylene radical contg. at least 2C opt. substd. by hydroxyl or alkoxy; the substits. present on the substd. hydrocarbon radicals represented by R2, R3, R9, R10 and R11 are selected from halogen, epoxy, amino, mercapto and 3-methacryloxpropyl; X = hydrolysable gp.; m = 2 or 3; n = 1 or 2; and p, s = 0, 1, 2 or 3.</p> |
