PURPOSE:To provide a polypropylene resin composition reduced in the deterioration of physical properties such as impact resistance and thermal deformation temperature by compounding a combustion ash having a specific average particle diameter and a specific surface area and a specific additive to a polypropylene resin. CONSTITUTION:A resin composition comprises (A) a polypropylene resin, (B) 5-50 wt.% of combustion ash having a wt. average particle diameter of 1-20mum and a specific surface of 10X10<3> cm<2>/g and (C) at least one of a polyhydric alcohol ester, polyamine and polyester condensate of formula I-III [R1, R3, R6 are methyl, ethyl; R2, R4, R5, R7 are 12-22C alkyl; M is alkaline earth metal such as Ca or Ba, Pb, Zn and Sn (but being electrically positive divalent); (n) is polymerization degree of <=1000] in an amount of <=0.1 pt. wt. per 100 pts. wt. of the total amount of the components A and B. |
