Abstract

Propunerea se refera la un procedeu de obtinere a copolimerilor etilenei cu alfa-olefine prin reactia de copolimerizare a etilenei cu 1-butena, 1-hexena sau 1-octena, la temepartura de 20-250 degree C, în prezenta unui catalizator constituit dintr-un compus cu formula fenerala: (vezi formula) în care vX reprezinta un halogen M' si M'' sînt metale diferite reprezentînd Mg, Al, Ti, V, Mn, Cr, Mo, Ca, Zn, Y, Y', si Y'' reprezinta halogeni identici sau diferiti de X, m si q pot fi zero sau diferiti de zero, dar nu simultan zero, n si p reprezinta valentele lui M' si M'', s poate avea o valoare cuprinsa între zero si trei, R' reprezinta o hidrocarbura alifatica cu pîna la 10 atomi de carbon.
