Process for the preparation of ethylene copolymers, and their use as additives to mineral oil and mineral oil distillates

   
   

The invention relates to a process for the preparation of terpolymers of ethylene and at least 2 further olefinically unsaturated compounds by polymerization in a tubular reactor fitted with at least one side branch, wherein the fresh monomer components, which are introduced into the tubular reactor via the reactor inlet (the primary stream) or via the side branch or side branches (secondary stream or secondary streams), in each of the streams contain ethylene and at most one further olefinically unsaturated compound.

L'invenzione riguarda un procedimento per la preparazione dei terpolimeri di etilene ed almeno di 2 ulteriori residui olefinically insaturi tramite polimerizzazione in un reattore tubolare misura con almeno un ramo laterale, in cui i componenti freschi del monomero, che sono introdotti nel reattore tubolare via l'ingresso del reattore (il flusso primario) o via i rami laterali del lato o del ramo (flusso secondario o flussi secondari), in ciascuno dei flussi contengono l'etilene e tutt'al piĆ¹ un ulteriore residuo olefinically insaturo.
