Process for preparation of styrene resin composition and styrene resin composition
First Claim
1. A process for preparing a styrene resin composition which comprises subjecting to bulk or bulk-suspension polymerization a solution obtained by dissolving a modified styrene polymer (A) in a styrene monomer (C), said modified styrene polymer being obtained by introducing directly or through another atomic group at least one functional group represented by the general formula into the styrene polymer chain obtained by polymerizing 90 to 100% by weight of a styrene monomer with 0 to 10% by weight of a monomer copolymerizable with the styrene monomer.

into the polymer chain of a styrene polymer obtained by polymerizing 90 to 100% by weight of a styrene monomer with 0 to 10% by weight if a monomer copolymerizable with the styrene monomer, if desired together with (B) a rubber-like polymer in (C) a styrene monomer.
