| Abstract: | This paper dealt with the synthesis of high trans-1,4-polyisoprene with supported titanium catalyst and triisobutylaluminium. Researches focused on the catalytic activity,earlytime polymerization rate of this catalystic system and the characterization of obtained polymers. The catalystic system gave high catalytic activity, catalytic efficiency was as high as 3000gTPI/gTi in certain extent,and high trans-1, 4-unit content , the trans-1, 4-unit was as high as about 98%. The activity energy was calculited,which was 33. 5kJ/mol. |
