Abstract
An ethylene terpolymer wax comprising, as monomer building blocks, from 35 to 95% by weight of ethylene, from 0.1 to 40% by weight of at least one ester of the formula I where R1 is selected from hydrogen, C1-C10-alkyl, C3-C12-cycloalkyl and C6-C14-aryl R2 are identical or different and are selected from hydrogen and C1-C10-alkyl, R3 is selected from C1-C10-alkyl, C3-C12-cycloalkyl and C6-C14-aryl and n is an integer from 2 to 100, and from 0.1 to 25% by weight of at least one carboxylic acid of the formula II where R4 is selected from hydrogen, C1-C10-alkyl, C3-C12-cycloalkyl and C6-C14-aryl.

A process for the preparation of an ethylene terpolymer waxes, wherein said ethylene terpolymer wax comprises, as monomer building blocks,
- from 35 to 95% by weight of ethylene,
- from 0.1 to 40% by weight of at least one ester of the formula I
- where R1 is selected from hydrogen. C1-C10-alkyl, C3-C12-cycloalkyl and C6-C14-aryl
- R2 are identical or different and are selected from hydrogen and C1-C10alkyl
- R3 is selected from C1-C10-alkyl, C3-C12-cycloalkyl and C6-C11-aryl and
- n is an integer from 2 to 100,
- and from 0.1 to 25% by weight of at least one carboxylic acid of the formula II
