Process for the preparation of ethylene copolymers comprising the copolymerization of ethylene with olefins CH&#x2550;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 C-Chydrocarbon group, Ris methyl or ethyl, optionally containing a heteroatom, and Ris a C4-C12 linear alkyl optionally containing a heteroatom, and (ii) an organo-Al compound. The obtained copolymers are endowed with good comonomer distribution. 

Process for the preparation of ethylene copolymers

A process for preparing porous olefin polymers comprising bringing into contact in a polymerization reactor, at a temperature T, one or more olefins of the formula (I) CH&#x2550;CHR, Rbeing hydrogen, a C&#x2013;C-alkyl or a C&#x2013;C-aryl group, with a catalyst obtained by reacting a solid catalyst component in the form of spheroidal particles comprising a compound of Ti or V not containing metal-&#x3c0; bonds and a Mg halide, optionally containing one or more electron donor compounds, with an aluminum-alkyl (Al-alkyl) compound, then raising the temperature up to the polymerization temperature, said process being characterized in that: a) if the temperature Tis lower than 40&#xb0; C., the temperature is raised up to the polymerization temperature is such a way that, for a time of at least one minute after the introduction temperature in such a way that, for a time of at least one minute after the introduction of the catalyst system into the reactor, the temperature of the reaction Tfulfills the following condition of formula (II) wherein m is the time expressed in minutes employed for reaching the temperature T; or b) if temperature Tis 40&#xb0; C. or higher, the reactor is maintained for a time of at least one minute at a temperature of at least 40&#xb0; C.

Process for the preparation of porous polymers and polymers obtainable thereof
