A process for improving hydrocarbons, in particular lubricating oils

Paraffin waxes and hydrocarbon lubricating oils and greases are improved by addition of a small proportion, e.g. 0,5--10,0 per cent of one or more highly polymerized vinyl compounds containing oxygen, i.e. polymers of m.w. about 1,000 but preferably 3,000--10,000. The waxes become softer, and are less liable to acquire fissures, and are thus suitable for making candles. The lubricants have their pour points lowered, and their viscosity indices raised. The polymers may be formed in the wax, oil or grease, or in other oils to be added thereto; other polymerizable substances, e.g. iso-olefines may be present; and the polymers may be hydrogenated or otherwise modified chemically.
