    • PROBLEM TO BE SOLVED: To provide a resin modifier comprising 1-butene-based polymer having uniform composition, controlled stereoregularity, high flowability and high flexibility. SOLUTION: The modifier for polyolefin-based resin comprises a 1-butene-based polymer satisfying following (1) to (3). (1) The intrinsic viscosity [η] as measured in tetralin solvent at 135°C is 0.01 to 0.5 dL/g. (2) The crystalline resin has a melting point (Tm-D) of 0 to 100°C, wherein the melting point is defined as the top of the peak observed on the highest-temperature side in a melting endothermic curve obtained with a differential scanning calorimeter (DSC) in a test in which a sample is held in a nitrogen atmosphere at -10°C for 5 min and then heated at a rate of 10°C/min. (3) The stereoregularity index ä(mmmm)/(mmrr+rmmr)} is 30 or lower. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供一种包含具有均匀组成,受控的立构规整性,高流动性和高柔性的1-丁烯基聚合物的树脂改性剂。 解决方案:聚烯烃类树脂改性剂包含满足以下(1)〜(3)的1-丁烯类聚合物。 (1)在135℃下在四氢化萘溶剂中测定的特性粘度[η]为0.01〜0.5dL / g。 (2)结晶性树脂的熔点(Tm-D)为0〜100℃,其中熔点定义为在用差分获得的熔融吸热曲线中在最高温度侧观察到的峰的顶部 将样品在氮气气氛中在-10℃保持5分钟,然后以10℃/ min的速度加热的试验中的扫描量热计(DSC)。 (3)立构规整度指数ä(mmmm)/(mmrr + rmmr)}为30以下。 版权所有(C)2007,JPO&INPIT
