Document Type and Number:
WIPO Patent Application WO/2019/004311
Kind Code:
A1
Abstract:
Provided is an injection-molded article which is of a polypropylene resin composition and which has excellent fluidity, flash prevention, and impact resistance. The polypropylene resin composition contains (A) a conjugated diene-modified propylene-ethylene block copolymer having a melt flow rate of 1-150 g/10 min as measured at 230ºC and a load of 2.16 kg, and (B) a polypropylene resin having a melt flow rate of 1-100 g/10 min as measured under the afore-mentioned conditions. The contained amount of (A) is 0.1-50 parts by weight and the contained amount of (B) is 99.9-50 parts by weight with respect to a total of 100 parts by weight of (A) and (B). The polypropylene resin composition has a melt flow rate of 10-100 g/10 min as measured under the afore-mentioned conditions, and a melt tension of 0.3-30 gf as measured at 200ºC and 20 m/min.
