| 摘 要： | 对聚合产品的分子量分布实现在线控制是保证高分子产品质量的重要任务。以实验室规模的乙烯基丁基醚管式阳离子聚合反应为研究对象,验证了单体、引发剂周期进料对分子量分布有加宽效应,并从混合平均分布的角度研究了周期进料对分子量分布的影响,从而分析了实现分子量分布控制的可行性。

| Abstract: | The on-line controlling molecular weight distribution of polymerization products works as a main task to guarantee the quality of polymer products.A research was conducted to testify the widening effect that monomer,initiator periodic operation exerted on molecular weight distribution on the basis of cationic polymerization reaction in a tubular reactor of vinyl butyl ether（VBE） in lab-scale as well as the effect of periodic operation on molecular weight distribution from mixed average distribution.Thus the accessibility of molecular weight distribution controlling was achieved. |
