Abstract
Procedeul de obtinere a unui catalizator utilizat la polimerizarea alfa-olefinelor, constî în aceea ca: (I) se supune reactiei o halogenura aleasa între clorura, bromura sau iodura de magneziu cu un fosfit organic cu formula: (vezi formula) în care R1, R2 si R3 reprezinta fiecare un radical alchil continînd 1...20 atomi de carbon, gupa aril sau aril substituita în care gruparea aril contine 6...18 atomi de carbon, iar substituentul alchil contine 1...20 atomi de carbon; (II) dupa care produsul de reactie astfel obtinut se copilverizeaza cu un complex de halogenura de titan aleasa dintre TiCl3 sau TiCl4 si un donator de electroni, ales dintre benzoatul de metil, n si i-butil, n-propil, n si i-amil, n-hexil, n-octil, 2-etil-hexil; (III) în final produsul copulverizat se supune reactiei cu TiCl3 sau TiCl4, cantitatea de fosfit organic aflîndu-se în concentratie de 0,01...10 moli/fosfit/mol compus de magneziu, iar cantitatea de titan din halogenura de titan este cuprinsa între 0,01% si 10%, în greutate exprimata cu totan metalic.
