Method of preparing silicon compositions

Abstract

A method of preparing a uniform silicone composition, comprising treating under the application of a shearing force a polymeric product obtained by addition polymerization of (A) an organhydrogenpolysiloxane containing in its molecule from 1.5 to 5 silicon-bonded hydrogen atoms on average, said silicon-bonded hydrogen atoms being in an amount of from 1 to 20 mol %, based on the total of the silicon-bonded hydrogen atoms and silicon-bonded organic groups in the molecule; and (B) an organopolysiloxane containing in its molecule from 1.5 to 5 silicon-bonded aliphatic unsaturated groups on average; in the presence of from 10 to 1,000 parts by weight of low-viscosity silicone oil having a viscosity of not more than 100 cSt at 25.degree. C. based on 100 parts by weight of the total amount of said (A) and (B).
