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.
