СПОСОБ ПОЛУЧЕНИЯ СОПОЛИМЕРОВ ЭТИЛЕНА

摘要

Process for the preparation of ethylene copolymers comprising the copolymerization of ethylene with olefins CH₂-CHR, in which R is a hydrocarbyl radical with 1-12 carbon atoms carried out in the presence of a catalyst comprising (i) a solid catalyst component comprising Mg, Ti, halogen and specific 1,3-diethers of formula (I) in which R is a C₁-C₁₀ hydrocarbon group, R₁ is methyl or ethyl, optionally containing a heteroatom, and R₂ is a C4-C12 linear alkyl optionally containing a heteroatom, and (ii) an organo-Al compound. The obtained copolymers are endowed with good comonomer distribution.
