<p>Low-melting, easily processable and at the same time hard polar waxes are obtained by treating copolymers, which are composed of ethylene and 0.5 to 50% by weight of a monomer containing oxygen-containing groups and have melt indices (MFI 190/2) of between 0.01 and 400 g/10 minutes, in the molten state, dispersed in a dispersing agent which is inert towards oxygen, with oxygen or oxygen-containing gases. Preferably, ethylene/vinyl acetate copolymers are oxidized, and these oxidation products are particularly suitable as the wax component in water-based and/or organic solvent-based polishes and in pastes.</p> |
