Abstract

The suspension polymerization in octafluorobutane, initiated by Ziegler–Natta catalyst system, has been used to synthesize ultra-high molecular weight poly(1-hexene), poly(1-octene), and poly(1-decene) of regular structure with high yields. This technique makes it possible to successfully carry out reactions at close to room temperature, followed by easy isolation of polymer products. The regularity of the structure of the synthesized polymers was proved based on the data of ¹H and ¹³C NMR spectroscopy. Using gel permeation chromatography, data on the molecular weight distribution of polymer molecules were obtained. They indicated that the weighted average mass of the synthesized polymers is many times higher than the mass of polyolefins produced by the classical technique of homogeneous polymerization.

八氟丁烷介质中规则结构超高分子量聚烯烃的合成

摘要

由齐格勒-纳塔催化剂体系引发的八氟丁烷悬浮聚合已被用于合成具有规则结构的超高分子量聚（1-己烯）、聚（1-辛烯）和聚（1-癸烯）。产量。该技术可以在接近室温下成功进行反应，然后轻松分离聚合物产物。根据¹ H 和¹³的数据证明了合成聚合物结构的规律性C 核磁共振光谱。使用凝胶渗透色谱，获得了聚合物分子的分子量分布数据。他们指出，合成聚合物的加权平均质量比采用经典均相聚合技术生产的聚烯烃质量高许多倍。
