Abstract

PURPOSE:To provide a composition having high rigidity and impact strength and manufacturable without restriction in the process, by adding an organic polysiloxane to a rubber-modified styrene resin composition having a specific resin structure. CONSTITUTION:A rubber-modified styrene resin wherein a rubbery polymer having the content of high-cis-polybutadiene containing >=90mol% cis-1,4-bond of >=70wt% is dispersed as soft component particles having an average particle diameter of 0.5-2.5mu, is compounded with an organic polysiloxane as a silicon component. The compound of the organic polysiloxane is 0.005-0.2pt.wt. per 100pts. of the composition, and that of the rubber polymer is preferably 2-10pts. The composition can be prepared by polymerizing a styrene monomer in the presence of the rubber polymer. The polysiloxane can be added to the composition at an arbitrary stage; however, it is preferable to add the compound to the monomer or in the extrusion step.
