PURPOSE:To obtain the composition having excellent process stability during molding and processing, slight feeding failure during injection molding, etc., comprising a 3-methylbutene-1 polymer, a graft modified 3 methylbutene-1 polymer, a fiber reinforcing material and titanium oxide. CONSTITUTION:(A) A 3-methylbutene-1 polymer having 0.1-100g/10 minutes melt index measured at 320 deg.C under 2.16kg load and >=30j/g heat of fusion measured by a Differential scanning calorimeter is blended with (B) a graft modified 3 methylbutene-1 polymer having 0.1-1,000g/10 minutes melt index measured at 320 deg.C under 2.16kg load and 0.1-5wt.% of a graft amount of an alpha, beta-unsaturated carboxylic acid (derivative) composition unit, (C) a fiber reinforcing material and (D) titanium oxide in the ratio of 90-99.9wt.% of the component A and 0.1-10wt.% of the component B in the components A and B and 25-100 pts.wt. content of the component C and 0.1-3 pts.wt. content of the component D to provide the polymer composition. |
