Abstract

The radical (co)polymerisation of ethylene is carried out in a stirred autoclave reactor as in parent patent but at >220 degrees C and under press. >1,000 bars, in the presence of O2, a peroxide or perester as initiator, and =500 ppm (w.r.t. ethylene) cpd. A which is a 5-12C cyclic olefin having a 5-9C ring, or styrene, possibly alkyl substd. in the benzene ring. The initiator consumption can be reduced by up to 75% when cpd. A is introduced with the initiator at 200 or 250 degrees C, compared with a redn. of =30% when introduced at 140 degrees C.
