聚乙烯(PE)是一种重要的合成树脂,具有广泛的用途。在生产高密度聚乙烯(HDPE)或线型低密度聚乙烯(LLDPE)的过程中,通过加入碳原子数大于3的不饱和烯烃与乙烯共聚,可以降低聚合物的密度,从而控制产品的熔体流动指数(MIR),改善机械加工性能和耐热性能。共聚单体的含碳数目越高,聚合物的综合性能越佳。目前,PE的共聚单体类型
Polyethylene (PE) is an important synthetic resin with a wide range of uses. In the production of high density polyethylene (HDPE) or linear low density polyethylene (LLDPE), the addition of carbon atoms greater than 3 unsaturated olefin copolymerization with ethylene, you can reduce the density of the polymer to control the product melt Body flow index (MIR) to improve machinability and heat resistance. The higher the carbon number of the comonomer, the better the overall performance of the polymer. Currently, the type of comonomer of PE
