Abstract

Inventia se refera la un procedeu de reducere a alcoxizii metalelor de tranzitie, selectate dintre: Ti-tetravalent, V tetravalent si pentavalent, Zr tetravalent, la alcoxizii corespunzatori cu valenta inferioara prin reactia dintre acesti alcoxizi ai metalelor cu valenta superioara în faza lichida, cu vapori ai metalelor cu valenta superioara în faza lichida, cu vapori ai metalelor alese dintre calciu, magneziu, aluminiu, la o temperatura de -80...+20 degree C. S-au obtinut astfel catalizatori foarte eficienti pentru polimerizarea compusilor nesaturati.
