Abstract

Inventia se refera la un procedeu pentru polimerizarea ciclopentenei cu deschidere în inel, în mediu de solvent inert, la temperatura de 5 degree C si în prezenta unui sistem catalitic tricomponential Ziegler-Natta, constînd în aceea ca, în mediu de reactie, se introduce un catalizator constituit din hexaclorura de wolfram în concentratie de 0,25...0,5 mmol/100g ciclopentena utilizînd, drept activator, acidul cianuric sau un derivat al acestuia, ales dintre clorura de izocianuril, 2hidroxi-4,6-diamino-S-triazina, sarea de sodiu a 2-hidroxi-4,6-diclor-S-triazina, acesta fiind în raport echimolar cu hexaclorura de wolfram.The invention relates to a process for polymerizing ring-opening cyclopentene in an inert solvent medium at a temperature of 5 ° C and in the presence of a Ziegler-Natta tricomponent catalyst system, characterized in that in a reaction medium a a catalyst consisting of tungsten hexachloride in a concentration of 0.25-0.5 mmol / 100g of cyclopentene using cyanuric acid or a derivative thereof selected from isocyanuryl chloride, 2-hydroxy-4,6-diamino-S -triazine, the sodium salt of 2-hydroxy-4,6-dichloro-S-triazine, being in an equimolar ratio with tungsten hexachloride.
