Abstract
PURPOSE: Polypropylene composition, improved in impact resistance without the reduction of rigidity, which comprises a proylene polymer and precipitated calcium carbonate of secified particle size.
CONSTITUTION: A composition comprising 30W90wt% of a propylene polymer and 70W10wt% of precipitated calcium carbonate of mean particle size of 0.16W1.0μ. In order to improve the mold flow, the melt flow rate of the polymer is prefereably 0.01W30g/10min. The isotactic index which represents wt% of n-heptane-insoluble fraction is preferably ≥90, specially ≥95 in view of the rigidity. The propylene polymer used is stereoregular propylene homopolymer, propylene-ethylene block copolymer, maleic anhydride-propylene graft copolymer, etc.
