processo para a fabricação de homo e copolímeros de etileno e uso de um c3 a c4 hidrocarboneto ou uma mistura dos mesmos

The present invention relates to the high pressure polymerization of ethylene and optionally comonomers using organic peroxides as polymerization initiators. The peroxide initiators are dissolved in a C3 to C6 hydrocarbon solvent. In one embodiment, the organic solvent at the same time acts as a cha...

Beschreibung
Zusammenfassung:	The present invention relates to the high pressure polymerization of ethylene and optionally comonomers using organic peroxides as polymerization initiators. The peroxide initiators are dissolved in a C3 to C6 hydrocarbon solvent. In one embodiment, the organic solvent at the same time acts as a chain transfer agent. In another embodiment, a chain transfer agent different from the organic solvent is used.
