    摘要: A polydiorganosiloxane emulsion having a combination of high polymer content and low viscosity can be produced by blending a high polymer content polydiorganosiloxane macroemulsion, having a polymer content of greater than 60 percent by weight and an average particle size of greater than 0.14 micrometers, and a high polymer content polydiorganosiloxane microemulsion, having a polymer content of from 20 to 30 percent by weight and an average particle size of less than 0.14 micrometers, with the ratio of the average particle size of the macroemulsion to the average size of the microemulsion of from 5 to 15.
