Abstract:
Disclosed is a method for producing powder of a vinyl polymer containing a silicone polymer, which comprises the step of spray-drying a latex of the vinyl polymer containing a silicone polymer obtained by polymerization of a vinyl monomer in the presence of a latex of the silicone polymer, wherein 3.0 mmol or less of a sulfate is contained in 100 g of the powder of a vinyl polymer containing a silicone polymer. According to the present invention, a powder which can provide a shaped article excellent in impact resistance and hydrolysis resistance in the case when the powder is blended in a resin such as polycarbonate resin can be obtained.
