Abstract

Ultra-high-molecular-weight polyethylene (UHMWPE) with an elevated melting point T_m of up to 144°C has been successfully fabricated by suspension polymerization initiated by Ziegler–Natta catalysts in a 1H,4H-octafluorobutane medium. This method allows one to efficiently perform the polymerization at a near-ambient temperature and a near-atmospheric ethylene pressure. The obtained polyethylenes have been characterized by IR spectroscopy, elemental analysis, and thermal analysis, and the melting points and degrees of crystallinity of the synthesized polymers have been found.

在八氟丁烷介质中合成高熔点超高分子量聚乙烯

在1H, 4h -辛氟丁烷介质中，采用Ziegler-Natta催化剂引发悬浮聚合，成功制备了熔点Tm高达144℃的超高分子量聚乙烯(UHMWPE)。这种方法可以在接近环境温度和接近大气的乙烯压力下有效地进行聚合。用红外光谱、元素分析和热分析对合成的聚乙烯进行了表征，并确定了聚合物的熔点和结晶度。
