单反应器双峰PE100管材料UHXP4806的结构与性能
|
摘要
采用凝胶渗透色谱分析(GPC)、差示扫描量热仪(DSC)及旋转流变分析等手段,通过和进口料对比,研究了单反应器双峰聚乙烯(PE100)管材料UHXP4806的结构与性能。结果表明:与进口料相比,UHXP4806的相对分子质量呈现双峰分布,且相对分子质量分布较窄;但重均相对分子质量含量较高,长链支化较多,系带分子的含量较高。
By the means of gel permeation chromatography(GPC), differential scanning calorimetry(DSC) and rotational rheology analysis,the structure and properties of single reactor bimodal PE100 pipe UHXP4806 were studied by comparing with imported materials. The results show that the relative molecular mass of UHXP4806 exhibites a bimodal and narrower distribution, compared with imported materials.But the weight-average relative molecular mass content of UHXP4806 is higher, the numbers of long-chain branching are more, and the content of laced molecules is higher.
