Title
(EN) METHOD FOR PREPARING DIALKYL MAGNESIUM COMPOUNDS BY ETHYLENE POLYMERISATION AND USES THEREOF
(FR) PROCEDE DE PREPRATION DE DIALKYLMAGNESIENS PAR POLYMERISATION DE L'ETHYLENE ET LEURS APPLICATIONS
Abstract
(EN)
The present invention relates to a method for preparing, by ethylene polymerisation, at least one dialkyl magnesium compound with formula R-(CH2-CH2)n-Mg-(CH2-CH2)m-R' in which R and R', optionally identical, are aryl, benzyl, allyl or alkyl groups and in which the n and m integers, optionally identical, are mean numbers of the -CH2-CH2- chain which are greater than 1, said method including a single step of mixing the following components: at least one ligand or a ligand precursor, at least one rare earth salt, at least one dialkyl magnesium compound with formula R-Mg-R', and ethylene, in a medium that enables contact between the components of the above mixture.
