Abstract

Inventia se refera la un procedeu de polimerizare a alfa-olefinelor, care are loc la o temperatura de 40...210 degree C si la o presiune de 7...70 kgf/cm2, în solutie, suspensie sau în faza gazoasa, eventual, în prezenta hidrogenului, pentru reglarea greutatii moleculare în prezenta unui catalizator, format dinmtr-o componenta (A) constînd dintr-un promotor organo-metalic, ales dintre alchil, hidruri, alchilhidruri si alchilhalogenuri ale metalelor din grupele Ia, II a, IIb, IIIa, si IVa, a sistemului periodic si un suport (B) insolubil în hidrocarburi. Procedeul conform inventiei permite sa se obtina poliolefine avînd greutati moleculare cuprinse între 50000 si 3000000 cu randamente mari, eliminîndu-se faza de separare a reziduriilor de catalizator.The invention relates to a process for the polymerization of alpha-olefins, which takes place at a temperature of 40 ... 210 ° C and at a pressure of 7 ... 70 kgf / cm2, in solution, suspension or in the gaseous phase, (A) consisting of an organo-metallic promoter selected from alkyl, hydrides, alkyl halides and alkyl halides of the groups Ia, IIa, IIa, IIb, IIIa, and IVa of the periodic system and a hydrocarbon insoluble support (B). The process according to the invention allows to obtain polyolefins having molecular weights ranging from 50000 to 3000000 in high yields, eliminating the phase of separation of the catalyst residues.
