摘要： The present invention provides a polyorganosiloxane-containing resin decreased in volatile siloxane content. A resin which contains 5% or more of volatile silicon compounds immediately after coagulation and dehydration is mixed with an organic solvent, and the resultant mixture is filtered to decrease the content of the volatile silicon compounds in the resin. Therefore, the target polyorganosiloxane-containing resin decreased in volatile siloxane content can be obtained. Mixing the polyorganosiloxane-containing resin and a thermoplastic resin and/or a thermosetting resin gives a resin composition having improved strength.
