Abstract

PURPOSE: To prepare a modified aromatic polycarbonate resin useful as a component of electronic equipments etc. and having improved moldability and mechanical properties, by polymerizing a monomer (e.g. a vinyl monomer) in an aqueous dispersion comprising the monomer and a particulate aromatic polycarbonate resin containing a specific amount of a lubricant.
CONSTITUTION: An aqueous dispersion comprising (A) a particulate aromatic polycarbonate resin containing 0.05W5wt% of a lubricant (e.g. styrene oligomer, etc.) and (B) a vinyl or vinylidene monomer (e.g. styrene, etc.), is prepared by using a suspension stabilizer (e.g. tribasic calcium phosphate, etc.) and a suspension assistant (e.g. sodium dodecylbenzenesulfonate, etc.). A polymerization initiator is incorporated and (B) is polymerized at 50W150°C to give the modified resin having an average molecular weight of 50,000W300,000 and containing 1W40wt% of the polymer of (B).
