Résumé :

High molecular weight trans-poly(9,9-di-n-octylfluorene-2,7-vinylene) was prepared under reduced pressure in the presence of a well-defined Schrock-type catalyst, Mo(CHCMe2Ph)(N-2,6-Me2C6H3) [OCMe(CF3)2]2, in toluene. The effect of initial monomer concentration was found to be an important factor for preparing high molecular weight polymers with unimodal molecular weight distributions. © 2001 John Wiley & Sons, Inc.
