Embodiment Construction

[0018] Hereinafter, the polypropylene resin composition according to the embodiment of the present invention will be described in more detail. However, it will be apparent to those skilled in the art that these are provided only as examples of the present invention, and the scope of the present invention is not limited thereto, and various modifications can be made to the embodiments without departing from the scope of the present invention. kind of modification.

[0019] As used herein, the term "short chain branch (SCB)" in the "olefin-based copolymer" or "(polymer) fraction" contained therein may refer to Fractions contain shorter chains branched from the longest backbone in each polymer chain. The number of short chain branches can be calculated by cross-fractionation chromatography (CFC) analysis of "olefin-based copolymers" or "fractions" thereof, and can be compared with the number of short-chain branches contained in "olefin-based copolymers" or the respective polymer...

Abstract

The present invention relates to a polypropylene-based resin composition which exhibits mechanical properties such as excellent strength, etc. and has an improved impact strength, and to a molded article including the same. The polypropylene-based resin composition comprises: a polypropylene-based resin; and an olefin-based copolymer, wherein the composition comprises polymeric fractions defined by three different peaks at a given temperature when the olefin-based copolymer is analyzed by cross-fractionation chromatography (CFC).

Description

technical field [0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0122447 filed with the Korean Intellectual Property Office on September 23, 2016, the disclosure of which is incorporated herein by reference in its entirety. [0003] The present invention relates to a polypropylene-based resin composition exhibiting mechanical properties such as excellent strength and having a more improved impact strength. Background technique [0004] A polypropylene-based resin composition containing a polypropylene-based resin as a main component and containing various additives is widely used in various fields and applications, such as compositions for interior and exterior parts of automobiles. [0005] However, in such a conventional polypropylene resin composition, an impact-reinforcing material is generally contained to enhance the impact strength of the polypropylene-based resin. Unti...
