Abstract (en)

The composition comprises an oil based on paraffins and, additionally, from 0.05 to 0.25% by weight of at least one radical polymerisation inhibitor chosen from quinones, phenol derivatives, phosphites and alkyl thiodicarboxylates. It is employed for lubricating the compressor of a high-pressure ethylene polymerisation plant.
