Abstract:
A method for making an aqueous emulsion of amine functionalized organopolysiloxane particles having a total solids content in a range between about 5% by weight and about 60% by weight, comprising effecting reaction at a temperature in a range between about 25.degree. C. and about 110.degree. C., and in the presence of an effective amount of an acid catalyst surfactant, between (A) an aqueous emulsion of organopolysiloxane particles having a volume average particle diameter of at least about 300 nanometers, and (B) an amine functionalized organosilicon source material, wherein there is used by weight in a range between about 1 part and about 50 parts by weight of (B) per 100 parts of (A); andwherein said volume average particle diameter is substantially maintained upon functionalization.
