| titleOfInvention | High-fluidity high-rigidity high-toughness polyolefin composition and preparation method thereof |
| abstract | The invention relates to the field of polyolefin, in particular to a high-fluidity high-rigidity high-toughness polyolefin composition and a preparation method thereof. The polyolefin composition comprises: a component a: the high-crystallization homopolymerized polypropylene has the isotactic five-unit component content of more than 98 percent, the molecular weight distribution of less than or equal to 10, and the melt index of 120-200g/10min measured under the conditions of 230 ℃ and 2.16kg load; and (b) component b: copolymers of ethylene with propylene, containing from 40 to 50% by weight of ethylene; and a component c: a nucleating agent; the content of component a is 84 to 88 wt.%, the content of component b is 12 to 16 wt.%, and the content of component c is 0.05 to 3 wt.%, based on the total weight of components a and b. The polyolefin composition of the invention combines good balance of flowability, stiffness and impact properties. |
