Abstract
Provided are an organic fiber filler-containing polypropylene resin composition providing an article which is excellent in a moldability and a strength and an article obtained from the same. The organic fiber filler-containing polypropylene resin composition comprises a polypropylene resin satisfying the following equation and an organic fiber filler in a proportion of 1 to 250 parts by weight of the filler per 100 parts by weight of the resin composition: log MT>4.24×log [η]−1.2 (1) wherein MT represents a melt tension (unit: cN) of the polypropylene resin at 230° C., and [η] represents a intrinsic viscosity (unit: dl/g) of the polypropylene resin measured in tetralin at 135° C.
