Abstract

Process for preparing well saturated vulcanizable elastomeric copolymers of ethylene with higher alpha-olefins having the general formula CH2 = CHR where R is an alkyl radical with 1 to 6 carbon atoms; or copolymers of low unsaturation of ethylene, alpha-olefins and higher polyenes, characterized in that it comprises copolymerizing a composition of monomers in contact with a catalyst prepared by combining (a) a component chosen from the group consisting of hydrides and organometallic compounds of aluminum with (d) a component chosen from the group consisting of (1) the product obtained by the fixation of a halogenated titanium compound on a support comprising an anhydrous magnesium or manganese dihalide complexed, at least partially, with the Lewis base; or (2) the product obtained by contacting the halogenated Ti compound with a support comprising an anhydrous magnesium or manganese dihalide having a surface area greater than 5 m2/g in the presence of a lewis base; or (3) the product obtained by contacting the halogenated Ti compound with a support comprising an anhydrous magnesium or manganese dihalide and a Lewis base under conditions in which, in the absence of the base, the support reaches a surface area greater than 5 m/g; or (4) the product obtained by contacting the halogenated Ti compound with a support comprising a complexed anhydrous magnesium or manganese dihalide, at least partially, with a Lewis base under conditions in which the Mg or Mn dihalide is not complexed reaches a surface area greater than 5 m2/g; and in any of said cases, the total molar ratio between magnesium or manganese dihalide and Lewis base in the catalyst being from 1: 2 to 20: 1.
