【摘要】：机械球磨法是一种快速且环境友好,具有巨大潜力的无溶剂合成双金属氰化物催化剂(DMC)的合成方法。通过共聚络合剂辅助机械球磨法成功制备出了Zn-Ni双金属催化剂,经元素分析和红外光谱结果显示双金属催化剂中掺入了各种共聚络合剂;扫描电镜表明,由此产生的双金属催化剂是纳米级的。双金属催化剂在无溶剂、反应时间为6h、反应温度为110℃的条件下可高效催化环氧丙烷(PO)与邻苯二甲酸酐(PA)的开环聚合,在共聚反应中,催化剂显示相对较高的活性,以高产率得到高分子量和窄分子量分布的聚酯(PO-co-PA)。
[Abstract]:Mechanical ball milling is a rapid and environmentally friendly method for the synthesis of bimetallic cyanide catalysts (DMC) without solvent. Zn-Ni bimetallic catalyst was successfully prepared by mechanical milling assisted by copolymerization complexing agent. The elemental analysis and infrared spectrum showed that various kinds of copolymerization complexing agents were mixed in the bimetallic catalyst. The resulting bimetallic catalyst is nano-sized. Bimetallic catalysts can efficiently catalyze the ring-opening polymerization of propylene oxide (PO) and phthalic anhydride (PA) under the conditions of solvent free, reaction time 6 h and reaction temperature 110 鈩，
