An 8 liter polymerization reactor was charged with 70 parts (dry basis) of the latex of particle size enhanced butadiene-styrene rubber obtained in (2). After elevating the temperature to 60° C. in a nitrogen gas stream with stirring, 0.18 part of formaldehyde sodium sulfoxylate, 0.001 part of ferrous sulfate and 0.004 part of disodium ethylenediaminetetraacetate were added to the reactor. Graft polymerization was then carried out in the same manner as in Example 1 by using 30 parts of a monomer mixture of 14.7 parts of methyl methacrylate and 15.3 parts of styrene. The obtained graft copolymer had an average particle size of 7,800 angstroms and a refractive index of 1.537.
