  • Publication number: 20060257354
    Abstract: Ethylene copolymer waxes containing amino groups, and use thereof Ethylene copolymer waxes with a molecular weight Mw in the range from 1000 to 20 000 g/mol, which comprise, as copolymerized comonomers, (c) from 50 to 95% by weight of ethylene, (d) from 5 to 50% by weight of at least one comonomer which has at least one alkylated or cycloalkylated amino group, each of which has bonding via a spacer to a polymerizable group, (e) from 0 to 30% by weight of other comonomers, where all % by weight data are based on the entire weight of ethylene copolymer wax.
