Propylene resin compositions, process for the preparation thereof, and use thereof.

摘要

A propylene resin composition featuring good flexibility and transparency without producing sticky feeling, and comprising a polypropylene component and a copolymer component of propylene and ethylene, wherein (I) the amount of the component (hereinafter referred to as medium- to low-temperature eluting component) that elutes out at temperatures of up to 90 DEG C by the temperature rising elution fractionation method by using an o-dichlorobenzene solvent is from 50 to 99% by weight of the whole amount, the amount of the component (hereinafter referred to as high-temperature eluting component) that elutes out at temperatures of not lower than 90 DEG C is from 50 to 1% by weight of the whole amount, and the amount of the component (hereinafter referred to as low-temperature eluting component) eluting out up to a temperature of 0 DEG C is not larger than 10% by weight of the whole amount, and (II) the content of the ethylene units in the component eluting up to the temperature of 90 DEG C is not smaller than 4% by weight but is smaller than 20% by weight, and the content of the propylene units in the component eluting at temperatures of not lower than 90 DEG C is from 97 to 100% by weight.
