Abstract:
1. A composition comprising the hydrosilylation reaction product of: where the subscripts α, β, γ, δ, φ, and λ are zero or positive and β+δ+λ≧2, and the stoichiometric coefficient α has a value of such that ((β+δ+λ)/((b+d+f)−(g+h+i)−(k+m+o))) is 0.01 to 10 where Compound A is the reaction product of: in the presence of a noble metal hydrosilylation catalyst where the subscripts a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, are zero or positive and q is non-zero and positive, for mixtures of compounds the average values of each of the subscripts will most likely be non-integral, for specific compounds the subscripts will be integral, with k+m+o<b+d+f−g−h−i, p ranges from 0.4 to 4.0 and q ranges from 1 to 200, the ratio (b+d+f−g−h−i)/(((k+m+o)p)q) ranges from 50.0 to 0.01 and where the compounds: is the hydrosilylation product of the following reaction: where the stoichiometric coefficient β satisfies the following relationship: β+1≦b+d+f and b+d+f−g−h−i>0 with 1.5≦b+d+f≦100; 2≦a+b≦12; 0≦c+d≦1000; 0≦e+f≦10 and R with each R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , and R 11 independently selected for each molecular species from the group of C1 to C60 monovalent hydrocarbon radicals and each R Vi independently selected from the group of C2 to C60 monovalent alkenyl hydrocarbon radicals wherein said composition comprises a star branched siloxane compound.
