Abstract
Disclosed is a rubber-modified styrene-based resin comprising a styrene-based polymer forming a matrix and rubber-like polymer particles dispersed in the matrix like islands, each of the rubber-like polymer particles having a cross sectional structure where the styrene-based polymer particles are contained like islands-sea, wherein the rubber-modified styrene-based resin is constituted of 1-10 wt % of the rubber-like polymer and 99-90 wt % of the styrene-based polymer; the particle-diameter of the rubber-like polymer particle falls within a range of 1.0 to 5.0 μm; and a value of (styrene-based polymer weight/rubber-like polymer weight) in a methylethylketone-insoluble matter of the rubber-modified styrene-based resin falls within a range of 0.5 to 1.5.
