Abstract

Process for the production of polymers of propylene with a molecular weight greater than 20,000 constituted by macromolecules with a succession, essentially regular, of ch groups subscript 2 and ch-ch subscript 3 in a long linear chain which, when passed to the crystalline state takes, at least for long stretches of molecule, a regular structure, probably in the shape of a spiral, corresponding to an identity period of 6.4 aº (or a multiple of this value), due to a succession of groups -ch subscript 2 -chch subscript 3- ch subscript 2-chch subscript 3- ch subindex 2- chch subscript 3 in the paraffinic chain, characterized in that these polymers are obtained by polymerization of propylene, by means of initiators (catalysts) of an exceptional activity, containing aluminum alkyls and titanium compounds, particularly the mixture of aluminum-triethyl and titanium tetrachloride, operating at temperatures below 120º and low pressure.
