The present invention provides a polypropylene-based resin composition, which comprises of a) a polypropylene; b) an ethylene 1-octene copolymer in which rr&#x3c;1 (herein, r=k/k, r=k/k, kis a growth reaction rate constant when ethylene is added to a growth chain in which an end active site is ethylene, kis a growth reaction rate constant when octene is added to a growth chain in which an end active site is ethylene, kis a growth reaction rate constant when octene is added to a growth chain in which an end active site is octene, and kis a growth reaction rate constant when ethylene is added to a growth chain in which an end active site is octene); and c) an inorganic filling agent, and a part for vehicles manufactured by using the same.

Polypropylene-based resin composition and automobile parts using the same

The present invention relates to a preparation method of olefin polymers using a catalyst composition containing a transition metal compound. In detail, the present invention provides a preparation method of olefin polymer using a catalyst composition comprising a transition metal compound, wherein the preparation method comprises introducing a scavenger to a continuous solution polymerization reactor in a specific range of amount to give the olefin polymer with good productivity.

Process for preparation of olefin polymers

The present invention relates to an ethylene-alpha olefin copolymer comprising long chain branches (LCB), while having a narrow molecular weight distribution. The ethylene-alpha olefin copolymer can be prepared by a continuous solution polymerization process using an activated catalyst composition containing a Group 4 transition metal compound having a monocyclopentadienyl ligand, to which a quinoline amino group is introduced.

Long chain-branched ethylene-alpha olefin copolymer

The present invention relates to an ethylene &#x3b1;-olefin copolymer having a narrower molecular weight distribution, and a uniform distribution of comonomer. The ethylene &#x3b1;-olefin copolymer according to the present invention has a uniform comonomer distribution and exhibits a lower density in the same comonomer content, unlike conventional ethylene copolymers having a random or blocky comonomer distribution.
