It is preferable that the amount be 0.5 parts by weight, more preferably 0.5 to 10 parts by weight.

The physical properties were determined by referring to the general physical properties of the homopolypropylene resin, and the respective target physical property values were flexural strength: 200 kgf / cm 2 or more, flexural modulus: 1
0000 kgf / cm 2 or more, IZ value: 2.0 kgf
cm / cm or more, and those in which all of these physical properties were cleared were evaluated as ○, and those in which all of them could not be cleared were evaluated as x. Table 1 shows the results.
