摘要
采用凝胶渗透色谱(GPC)、13C-NMR、差示扫描量热法(DSC)等分析技术对无规共聚聚丙烯(PPR)管材的结构和性能进行研究。对PPR管材结构性能影响因素分析结果表明,熔体流动速率和熔点对PPR生产具有决定性的影响。
Structure and properties of random copolymer of propylene （PPR） pipes were studied by GPC, ^13C-NMR and DSC. The results show that the melting point and melt index have decisive effect on the production of PPR by analyzing the influence factors of structure and properties of PPR pipes.
