摘要：
The ring-opening metathesis polymerization (ROMP) of norbornene (NBE) and dicyclopentadiene (DCPD) catalyzed by Cp2TiCl2 (Cp = eta(5)-cyclopentadienyl) and a series of different RMgX (R = CH3, C2H5, i-C3H7, n-C4H9, n-C6H13, C6H5, X = Cl Pr, I) were studied. The catalytic system Cp2TiCl2/CH3MgI is the most active for the ROMP of NBE and DCPD, but Cp2TiCl2 with other Grignards appeared rather low catalytic activity. The mechanism of polymerization with Cp2TiCl2 and different Grignard agents was discussed. (C) 1998 Elsevier Science B.V. All rights reserved.
