Abstract:
1. A composition comprising: a) colloidal silica core/silicone shell particles comprising (i) about 90 wt % to about 10 wt % cores of colloidal silica and (ii) about 10 wt % to about 90 wt % shells of a polyorganosiloxane having the formula with M D T Q where R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 are each independently selected from the group consisting of OH, linear or branched monovalent hydrocarbon radicals of 1 to 30 carbons, monovalent arylalkyl, aryl cyclics hydrocarbon radicals where the ratios of M to D to T to Q are according to the following relationships: b) a polyalkyleneoxide modified trisiloxane having the formula: with M M D D where R 7 , R 10 and R 15 are each independently selected from the group consisting of or 1 to 4 monovalent hydrocarbon radicals or R 17 ; subject to the following relationship that when g=0 then R R R where the subscripts e, f, g and h are zero or 1 subject to the following relationship: with the requirement that when g is 0, then R 7 or R 10 are R 17 ; R where R 18 is a linear or branched hydrocarbon radical having from 2 to 6 carbons, R 19 is selected from the group consisting of H, acetyl or a monovalent hydrocarbon radical of 1 to 6 carbon atoms and the subscripts j, k, and m are zero or a positive integer subject to the limitation that 4<j+k+m≦20; c) an emulsifier comprising an anionic surfactant derived selected from the group consisting of alkylarylsulfonates, alkylsulfonates, alkylsulfates and alkylethersufates, alkyl phosphate esters, alkylaryl phosphate esters, alcoholalkoxylate phosphate esters, and alkylarylalkoxylate phosphate esters and mixtures thereof; and d) the salt of an acidic polymerization catalyst.
