A polyalkene coated porous filler useful as a packing material in high performance chromatography is stable towards solvents and strong acids or bases, and avoids excessive preparation costs due to the high solvent volumes required

摘要

A polyalkene coated porous filler is new. An Independent claim is included for preparation of the polyalkene coated filler involving dissolution of the polyalkene in a solvent, addition of a dry porous filler to the solution obtained, and evaporation of this solution to dryness. The thickness of the polymer layer is 0.5-5 nm.
