Title:
THERMOPLASTIC RESIN COMPOSITION, MOLDED ARTICLE AND MANUFACTURING METHOD OF MOLDED ARTICLE
Document Type and Number:
Japanese Patent JP2017203153
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve an impact resistance and to reduce a mold shrinkage factor.SOLUTION: A thermoplastic resin composition includes a polystyrene 11 being a major component and a dispersed rubber phase 12, and further includes: an impact resistant styrenic resin with a volume fraction of the dispersed rubber phase 12 being less than 30%; an elastomer dispersion phase 21, 22; and a filler particle 31. The elastomer dispersion phase 21, 22 includes, as a major component, a styrene-butadiene copolymer being a linear copolymer including a triblock of a butadiene block and styrene blocks linked respectively to both ends of the butadiene block.SELECTED DRAWING: Figure 1
