Patent ID: 7247672

Claim:
A process for producing a liquid non-aqueous dispersion having a copolymer dispersed in a silicone oil, which comprises copolymerizing (A) 1 to 20% by weight of at least one radical polymerizable macromonomer containing dimethyl polysiloxane, the macromonomer (A) being represented by the formula (1): (wherein X represents a radical polymerizable group, n is an integer of 1 to 10, and m is an integer of 3 to 300), and (B) 99 to 80% by weight of at least one radical copolymerizable monomer with said macromonomer (A), the monomer (B) comprising at least one (meth)acrylate monomer and optionally at least one vinyl monomer, by subjecting said monomers to one-step polymerization in a silicone oil in the presence of a radical polymerization initiator without a dispersion stabilizer.
