ANTISTATIC COMPOSITION

摘要

The invention relates to a composition that comprises a thermoplastic or elastomeric polymeric substrate (A) and an antistatic mixture (B) in the form of contiguous fibres, which mixture comprises (b1) an organic polymeric material that is fibrous or form s fibres on mixing and is not soluble in the thermoplastic or elastomeric polymeric substrate (A); (b2) a polymer or copolymer capable of ion conduction that has blocks for complexin g or solvating a salt of an inorganic or low-molecular-weight organic protonic acid (b3) an d has a better compatibility with the organic polymer (b1) that is fibrous or forms fibres on mixing than with the polymeric organic substrate (A); and (b3) a salt of an inorganic or low- molecular-weight organic protonic acid that has been complexed or solvated in the polymer or copolymer (b2). The invention relates also to the antistatic mixture (B) as such, to i ts use in rendering polymers antistatic and to a process for the preparation of antistatic thermoplastic or elastomeric polymeric substrates.
