Compositions comprising propylene-olefin-copolymer waxes and carbon black

摘要

The invention relates to compositions comprising certain propylene-olefin-copolymer waxes and carbon black (CB), the compositions being in the form of masterbatches, compounds or conductive polymers, and their use for producing conductive polymers and articles made of conductive polymers.

主权项

1. A composition Z comprising a component A and a component B, wherein
the component A is a propylene-olefin-copolymer wax, and the component B is a carbon black, wherein the propylene-olefin-copolymer wax is made of the monomers propylene and of from 0.1 to 50% by weight of at least one compound of formula (II), Ra is selected from the group consisting of H and unbranched or branched C2-18-alkyl;
wherein, the composition Z includes at least one wax other than the propylene-olefin-copolymer wax as component D, wherein the composition Z includes a component F, wherein the component F is at least one metal stearate, and wherein the composition Z comprises of from 25 to 90% by weight of component A, and from 10 to 40% by weight of component B; the % by weight being in each case based on the weight of the total composition Z.
