Popis: | 1. Allyl compounds of silicon in combination with tungsten halides effectively catalyze the ring-opening polymerization of cycloolefins. 2. Polymerization of cyclopentene by the catalyst system WCl6-tetraallylsilane between -20 and -78°C forms a polypentenamer with 94–99% cis-units. 3. We have studied the polymer-monomer equilibrium in the cis-polymerization of cyclopentene by the WC16- tetraallylsilane system and have determined some thermodynamic parameters for the process. |
