摘要
乙烯-辛烯共聚物(POE)因其特殊的分子链段结构,使其具有橡胶和塑料的双重特性。POE热塑性弹性体将成为广泛替代传统橡胶和塑料的极具发展前景的新型材料。熔体流动速率是POE的一项控制分析指标。介绍了通过预处理样品的方法,解决了测定POE样品熔体流动速率时样品黏裹加料杆、反复往外带料、挤出样条有大量气泡等系列问题。通过对照实验表明,处理样品过程未能改变POE原有的熔体流动速率,说明处理样品过程安全有效可行。
Because of its special molecularchain structure,ethylene-octylene copolymer（POE）,has the dual characteristics of rubber and plastics.POE thermoplastic elastomer shall become new materials which can replace the traditional rubber and plastic.In POE＇s research trials melt flow rate is a control analysis index.This article introduced the method of the sample pretreatment,it has solved the questions：adhere to charging stick,bring out material and extruding sample strip has many bubble.Check test showed that processing process can＇t change the POE melt flow rate of the original sample.The process of processing sample is safety and practicable.
