ABSTRACT:
The invention relates to a polymer blend and a process for its preparation. The polymer blend contains A) a polymer of an olefin and an unsaturated carboxylic acid, wherein the amount of acid groups is 0.5–15 molar %, and B) a polyether block polymer made up of a polyether block and a polyamide or polyester block, the acid groups in polymer A and the polyether blocks in polymer B having at least partly coordinated alkali ions, and an alkali metal being present in an amount of approx. 0.02–3 millimols/gram of the polymer blend. The blend according to the invention has a good electrical conductivity and excellent mechanical properties.
