ABSTRACT:
Disclosed is a process for producing a styrene polymer composition, which comprises polymerizing styrene monomer using a catalyst comprising (A) aluminoxane and (B) a compound of the group IV B transition metal in the periodic table, in the presence of rubber-like elastomer.
The resin composition obtained thereby is superior in heat resistance, and impact strength, and utilized as the starting material for various moldings.
