采用两种新型咪唑侧链官能化单茂锆{Ph2CN2C4H6CpZrCl3和PhCHN2C4H6CpZrCl3}与甲基铝氧烷(MAO)组成的催化体系进行降冰片烯的聚合,考察了不同温度、不同Al/Zr对催化效率的影响。得到了透明度高,能溶于有机溶剂,熔点高于400℃的聚降冰片烯。该催化体系在80℃、Al/Zr为500时催化活性最高,可达到104g PNBE/(molZr.h)。通过对聚合产物FTIR的分析,得到了不同条件下的主要聚合方式。
The polymerization of norbornene was carried out using two novel imidazole side-chain functionalized monocene zirconium {Ph2CN2C4H6CpZrCl3 and PhCHN2C4H6CpZrCl3} and methylaluminoxane (MAO). The effects of different Al / Zr on the catalytic efficiency influences. Get a high transparency, soluble in organic solvents, melting point higher than 400 ° C polynorbornene. The catalytic system has the highest catalytic activity at 80 ℃ and Al / Zr of 500, which can reach 104g PNBE / (molZr.h). Through the analysis of the polymerization product FTIR, we got the main polymerization under different conditions.
