摘要：
The present invention relates to a method for the radical polymerization or copolymerization of ethylene at high pressures using a hydroxylamine ester as radical initiator. The hydroxylamine esters according to the invention are suitable initiators for the high pressure polymerization of ethylene leading to high molecular weight polyethylenes with narrow molecular weight distributions (Polydispersed Index PD=1.2−4.5).
