| titleOfInvention | High Rigidity Propylene-Ethylene Block Copolymer Composition and Its Manufacturing Method |
| abstract | The present invention provides a high rigidity, high impact propylene-ethylene block copolymer composition and a method for preparing the same.n n n Using a specific Ziegler-Natta catalyst, [polymerization step (I)] two or more polymerization reactors are used to carry out homopolymerization of propylene to 60 to 95% of the total weight, with each reactor The maximum and minimum values of the melt flow rates of the polymers obtained inn n n [Polymerization Step (II)] One or more polymerization reactors were used, and propylene-ethylene random copolymerization was carried out to 5 to 40% by weight of the total weight,n n n Provided are a high rigid propylene-ethylene block copolymer composition and a method for producing the same, wherein the ratio of the melt flow rate of the polymerization step (I) to the melt flow rate of the polymerization step (II) falls within a specific range.n n n A copolymer which is remarkably superior to the known ethylene-propylene block copolymer in the overall strength of the injection molding machine can be obtained. |
