linear polyethylene (LPE)

In this paper shear elastic behaviours of linear polyethylene melt were quantitively and qualitively charactenized by rheological parameters such as elastic shear complince Je, recoverable elastic strain SR,melt die swell and so on.

利用稳态剪切柔量、可回复剪切应变以及熔体挤出胀大比等参数,定量计算和定性表征了4种线型聚乙烯熔体的剪切弹性行为,研究了各表征参数之间及其与分子量、分子量分布等分子参数的关系,讨论了剪切弹性行为对加工性能的影响。

线型聚苯乙烯支载脯氨醇的合成研究

Non-cross-linked polystyrene (NCPS) supported (4s)-4[(4-benzyloxy) benzyl] oxazolidin -2-one was obtained through radical polymerization of styrene and oxazolidione.

噁唑烷酮手性单体与苯乙烯经溶液聚合得到线型聚苯乙烯支载的(4s)-4-苄基-噁唑-2-烷酮手性助剂,经IR,NMR分析证实了其结构,DSC及TGA分析表明该聚合物具有较好的稳定性,考察了单体浓度对聚合物性能的影响。
