| Abstract: | Several important reaction conditions which was used in polymerization of syndiotactic polypropylene(sPP) were studied.The consumption of three reagents which affected polymerizing activity and molecular weight were observed. The three reagents were methylaluminoxane(MAO), triethylaluminum(TEA) and hydrogen. The consumption of the three reagents was optimized. The effects of polymerizing temperature and solvents on syndiotactic grade of sPP were studied. The kinetics of the polymerizing reaction was explored. The optimum conditions for polymerization of sPP were obtained. |
