Abstract
Process for the preparation of alpha-olefins polymers of high melting point, linear, head-to-tail, of alpha-olefins of formula CH 2 = CHR, wherein R is an alkyl radical of structure - (CH 2) n -CH (CH3) 2, in which n = 1, characterized in that alpha-olefins of the formula CH2 = CH- (CH2) n-CH (CH3) 2 are polymerized, in which n = 1, in the presence of catalysts obtained from transition metals of group 4, 5 and 6 of the periodic system, corresponding to a valence of said metals lower than the maximum valence, and of metal-alkyl compounds of metals of group 2 and 3 of the periodic system.
