  A propylenic polymer according to the present invention or a composition thereof have an excellent melt flowability and contains a less amount of stickiness-causing components, and also has a low modulus and is pliable, and is capable of providing a transparent molded article, thus being useful as a substitute for a pliable vinyl chloride resin. In addition, a molded article made therefrom exhibits an excellent heat seal performance at a low temperature, and is excellent in terms of transparency and rigidity. Specifically, it has an isotactic pentad fraction (mmmm), which indicates a stereoregulariry, of 30 to 80 %, a molecular weight distribution (Mw/Mn) of 3.5 or less and an intrinsic viscosity [η] of 0.8 to 5 dl/g.

  根据本发明的丙烯聚合物或其组合物具有极佳的熔体流动性，且含有较少的致粘成分，模量低且柔韧，能够提供透明的模塑制品，因此可用作柔韧氯乙烯树脂的替代品。此外，由其制成的模塑品在低温下具有出色的热封性能，在透明度和刚性方面也非常出色。具体来说，它具有 30% 至 80% 的异构五元组分 (mmm)，分子量分布 (Mw/Mn) 为 3.5 或更低，固有粘度 [η]为 0.8 至 5 dl/g。
