Abstract:
An organotin silane of the formula: ##STR13## wherein: each R.sup.1 is independently selected from the group consisting of F, Cl, Br, I, OR, and R, where R is substituted or unsubstituted C.sub.1 to C.sub.12 alkyl, C.sub.5 to C .sub.2 cycloalkyl, or aryl, provided at least one value of R.sup.1 is selected from among F, Cl, Br, I, and OR;each R.sup.2 is independently selected from R.sup.1, benzyl, vinyl, allyl, hydride, and ##STR14## provided at least one value of R.sup.2 is F, Cl, Br, I, or OR; R.sup.3 is (CH.sub.2).sub.m, aryl or cycloalkyl,m=0 to 17, n=1 to 18, sum of n plus m=1 to 18 except when R.sup.3 is aryl or cycloalkyl then n=at least 2,except, when R.sup.3 =(CH.sub.2).sub.m , n=1, m=0, and at least one value of R.sup.1 is Cl, F, OR, or when R.sup.2 is ##STR15## then, all of the remaining values of R.sup.2 cannot be selected from Cl and I and when one of the remaining selections for R.sup.2 is Cl or OR, then all the remaining values of R.sup.2 cannot be R; and,except also, when R.sup.3 =(CH.sub.2).sub.m, the sum of n plus m=2,4,5 or 6, all values of R.sup.1 are OR with R being aryl or C.sub.1 to C.sub.12 alkyl, one value of R.sup.2 is Cl, aryl or hydride;then, all remaining values for R.sup.2 cannot be selected from C.sub.1 to C.sub.12 alkyl, C.sub.7 to C.sub.18 cycloalkyl or aryl; and,except also, when R.sup.3 =(CH.sub.2).sub.m, the sum of n plus m=3, at least one value of R.sup.1 is Cl, all other values of R.sup.1 are selected from Cl, C.sub.1 to C.sub.12 alkyl, vinyl, or phenyl and one value of R.sup.2 is Cl,then, all remaining values of R.sup.2 cannot be selected from among Cl and methyl; andexcept also, when R.sup.3 =(CH.sub.2).sub.m, the sum of n plus m=4 or 5, all values of R.sup.1 are Cl, and two values for R.sup.2 are Cl then the remaining value for R.sup.2 cannot be butyl.
