PROBLEM TO BE SOLVED: To provide a polyolefin-based resin composition which is suitable as a substitute resin for a soft vinyl chloride resin and provides a molded article and a film having low stickiness, excellent softness and low-temperature impact resistance. SOLUTION: The 1-butene polymer [I] is composed of 1 to 99% by weight and the polyolefin [II] 99 to 1% by weight. Is melted at 190 ° C. for 5 minutes in a nitrogen atmosphere and then 5 ° C. / Min at −10 ° C., hold at −10 ° C. for 5 minutes, and then increase at 10 ° C./min. Defined as the peak top of the peak observed on the highest temperature side of the melting endothermic curve. (2) stereoregularity index of 20 or less, (3) molecular weight distribution of 4.0 or less, (4) weight average molecular weight of 10, 000 to 1,000,000 polyolefin-based resin compositions, molded articles and films thereof. |
