Abstract
The invention relates to a process for the preparation of a copolymer of ethylene and a monomer copolymerizable therewith.The polymerization takes place in a tubular reactor at a peak temperature between 290° C. and 350° C., the co monomer is a di- or higher functional (meth)acrylate and the co monomer is applied in an amount between 0.008 mol % and 0.200 mol % relative to the amount of ethylene copolymer.
