Abstract

A wax composition comprises at least three amide waxes A, B, and C, where amide wax A is the reaction product of alkylenediamine with linear fatty acids or with mixtures composed of fatty acids, amide wax B is the reaction product of alkylenediamine with 12-hydroxystearic acid, and amide wax C is the reaction product of alkylenediamine with 12-hydroxystearic acid and with linear fatty acids. The wax composition is suitable as a processing aid in engineering thermoplastics or for the preparation of solvent-based wax pastes or the preparation of wax micronizates for coatings or for the preparation of aqueous dispersions.

Claims (6)

1. A thermoplastic polymer comprising at least one thermoplastic polymer and a wax composition, wherein the wax composition comprises at least three amide waxes A, B, and C, wherein

amide wax A is the reaction product of alkylenediamine with linear fatty acids or with mixtures of fatty acids,

amide wax B is the reaction product of alkylenediamine with 12-hydroxystearic acid, and

amide wax C is the reaction product of alkylenediamine with 12-hydroxystearic acid and with linear fatty acids and wherein the wax composition is present from 0.1 to 10% by weight.

2. The thermoplastic polymer as claimed in claim 1 , wherein the wax composition is present from 0.2 to 5% by weight.

3. The thermoplastic polymer as claimed in claim 1 , wherein the wax composition is present from 0.2 to 2% by weight.
