## Abstract

The invention concerns a halogen-free polymeric blend capable of ionic conductivity comprising either one or more polyether-based polymers or copolymers that have favorable structures to facilitate polymer chain segmental motion and ion hopping environment, selected from the group of polyether-block-polymers and polyether-based polyurethanes, or said polyether based polymers or copolymers together with one or more ionomers formed by neutralization of ethylene acid co-polymers, as well as one or more specific halogen-free ionic complexes or salts comprising a weakly coordinating anion and a cation of an alkali metal or alkaline earth metal. Further, the invention concerns the use of said blend and a plastic material containing said blend as an additive.

## Claims

### Claim 1

An extrudable halogen-free polymeric blend capable of humidity independent ionic charge conduction which consists of a polyether-polyamide block copolymer and an ionic complex or salt selected from sodium bis(oxalato)borate and potassium bis(oxalato)borate and wherein the ionic complex is present in the polymeric blend in an amount of 0.002-0.05 millimols/gram of the polymeric blend.

### Claim 2 (depends on 1)

The polymeric blend according to claim 1 wherein the ionic complex or salt is potassium bis(oxalate)borate.

### Claim 3

An extrudable halogen-free polymeric blend capable of humidity independent ionic charge conduction which consists of a polyether-polyamide block copolymer, 10-30% by mass of one or more ionomers formed by neutralization of polymers of a co- or terpolymer of ethylene and acrylic or methacrylic acid, and an ionic complex or salt selected from sodium bis(oxalato)borate and potassium bis(oxalato)borate, wherein the ionic complex or salt is present in the polymeric blend in an amount of 0.002-0.05 millimols/gram of the polymeric blend.
