Abstract: In this paper, catalytic system TiCl4/Al2Et3Cl3/Yfor copolymerization of ethylene and propylene was studied by using IRand ESRtechniques.For the first time, it was found in TiCl.,/ Al2Et3Cl3/Ysystem there was one liquid catalytic species in solid phass.High catalytic effeciency reached to 10.2 kg P/g Ti·h when T=50℃, Al/Ti=50, P=101.325×103 Pa.

Key words: Coordination copolymerization, Supported catalyst, Zeolite
