摘要：

The cross-metathesis polymerization of norbornene with several unsaturated diesters was initiated by WCl6/Sn(CH3)4, in cyclohexane solution. This reaction leads to either hydroxyor carboxy-functionalized oligomers which have been characterized by C-13 and H-1 NMR. Their number average molecular weight decreases linearly when the ratio [ester]/[norbornene] increases, indicating that the ester acts as a good transfer agent. The influence of the diester structure on the molecular weight values was also studied in detail. A possible reaction mechanism is proposed.
