    Abstract: A polyolefine wax of oxygen content 0.08 to 10%, peroxide content 0.001 to 0.3% and of acid number of at least 1, is reacted with an organic compound containing at least one unsubstituted or substituted alkaline-reacting nitrogen atom. The wax may be prepared as described in Specification 959,362, and the nitrogen-containing organic compound may be an amide or imide of a saturated or unsaturated aliphatic or aromatic carboxylic acid, an aliphatic or cycloaliphatic amine, an heterocyclic compound, or a triacryl formal/amine reaction product. Nickel or aluminium salts of the modified waxes may be obtained by reaction with Ni or Al salts. The products improve the dyeability of polypropylene, in particular fibres thereof.
