Abstract
A propylene-based resin composition containing components (A), (B), and (C) is provided. The content of (A) is 50 to 89 parts by weight, the content of (B) is 11 to 50 parts by weight, and the content of (C) is 0.05 to 1 part by weight, based on 100 parts by weight of the total of (A) and (B). Component (A) is a propylene-based polymer, component (B) is a filler, and component (C) is a bis(3,4-dialkylbenzylidene)sorbitol represented by the formula (1) In formula (1), Rand Reach independently represent an alkyl group having 1 to 4 carbon atoms. It is possible to produce a molded article which has high rigidity and in which the linear expansion coefficients in the MD and the TD are small from the composition.
