Abstract
A process for the reduction of reactor fouling at radical initiated high pressure polymerisation of ethylene (co)polymers is described. The process is characterised in that an adhesion reducing silicon containing compound is added to the polymerisation reactor, preferably in an amount of 0.001-3% by weight, based on the amount of polymer produced. Preferably the silicon containing compound is hexadecyl trimethoxy silane.
