Abstract
Polymerization of propylene and isoprene were conducted with the catalytic systems of TiCl4/Al(C2H5)3 and TiCl4/MgCl2/Al(C2H5)3 using ethyl benzoate and 2,2,6,6-tetramethylpiperidine as Lewis bases. With increasing the concentration of these Lewis bases, the stereospecificities increased toward more isotactic and more trans-1,4-addition. The role of Lewis bases on the stereospecificities was proposed based on the result.Keywords
