Copolymerizations of ethylene with endo-dicyclopentadiene (DCP) were performed by using Cp 2 ZrCl 2 (Cp Ο Cyclopentadienyl), Et(Ind) 2 ZrCl 2 (Ind Ο Indenyl), and Ph 2 C(Cp)(Flu)ZrCl 2 (Flu Ο Fluorenyl) combined with MAO as cocatalyst. Among these three metallocenes, Et(Ind) 2 ZrCl 2 showed the high
Copolymerizations of 1,3-pentadiene (PD) with endo-dicyclopentadiene (DCPD) initiated by aluminum trichloride were carried out in toluene. The addition of DCPD in the PD polymerization system does not affect the molecular weight but increases greatly the softening point of the polymer due to the int
