Abstract

Procedeul pentru polimerizarea ciclopentenei obtinuta din fractiunea C5 cu continut ridicat de olefine, în mediu de solvent, la o temperatura de 5...10 degree C, caracterizat prin aceea ca în mediul de reactie se introduce un sistem catalitic format din hexaclorura de wolfram si triizobutil-aluminiu activat cu un amestec de cloranil si alcool etilic în proportie de 1:1,5...1:3, la o concentratie de 0,5 mmol WCl6 la un mol de ciclopentena.The process for the polymerization of cyclopentene obtained from the high olefin C5 fraction in a solvent medium at a temperature of 5 ... 10 ° C, characterized in that a catalytic system consisting of tungsten hexachloride is introduced into the reaction medium triisobutylaluminum activated with a mixture of chloranil and ethyl alcohol in a ratio of 1: 1.5 to 1: 3 at a concentration of 0.5 mmol of WCl6 per mole of cyclopentene.
