摘要
以环氧丙烷(PO)为原料，在乙酸酐存在下，以镁铁氢离子(maghni - h +)为催化剂，采用阳离子开环聚合法制备了端基为乙酸甲酯的远螺旋聚环氧丙烷(PPO)双大单体。镁氢离子是一种与质子交换的蒙脱土片状硅酸盐粘土。研究了乙酸酐用量和反应时间对聚合收率和分子量的影响。产物经核磁共振(1h - nmr)表征。
Telechelic of Poly (Propylene Oxide) Catalyzed by Maghnite-H+~!2009-05-16~!2009-09-09~!2009-12-31~!
Telechelic poly (propylene oxide) (PPO) bismacromonomers bearing methyl Acetate end groups, were prepared by cationic ring-opening polymerization of propylene oxide (PO), in the presence of Acetic anhydride, catalyzed by Maghnite-H + (Mag-H + ), in bulk. Mag-H + is a montmorillonite sheet silicate clay which was exchanged with protons. The influence of the amount of acetic anhydride and the reaction time on The polymerisation yield and molecular weight were studied. The products have been caracterized by Nuclear magnetic resonance ( 1 H-NMR).
