Document Type and Number:
WIPO Patent Application WO/2023/243587
Kind Code:
A1
Abstract:
Provided is a polypropylene resin composition which achieves an excellent balance of rigidity and shock-resistance and comprises a propylene polymer composition comprising a filler, and comprises a polyamide resin and a modified elastomer. Provided is a polypropylene resin composition containing a propylene polymer composition (a), a polyolefin composition (b), and an acid-modified polypropylene (c), wherein: the propylene polymer composition (a) comprises a propylene polymer (a1) and a filler (a2); the polyolefin composition (b) comprises a polyolefin (b1), an aliphatic polyamide resin (b2), and a modified elastomer (b3), and has a specific phase structure; and the modified elastomer (b3) is an elastomer in which a moiety comprising a group reactive with the aliphatic polyamide resin (b2) is added to a specific unmodified elastomer (b3').
