Lubricant is a mixture of high-molecular polymers of polymerizable double-bond compounds containing an aromatic group and cracking or dehydrogenation products of hydrocarbons or substances containing unsaturated components such as are obtained in the hydrocarbon synthesis from CO and H₂. The polymers are obtained with the aid of acid halides or materials of large surface area.
