Antistatic composition
First Claim
1. A composition comprising a thermoplastic or elastomeric polymeric substrate-forming material (A) and an antistatic mixture (B) in the form of contiguous fibres, which mixture comprises(b1) an organic polymeric material that is fibrous or forms fibres on mixing and is not soluble in the thermoplastic or elastomeric polymeric substrate-forming material (A) which is selected from the group consisting of a polyacrylic acid ester, polymethacrylic acid ester, polyacrylonitrile, polyvinyl alchol, polyvinyl acetate, polyamide, polyurethane or polyester;
- (b2) a polymer or copolymer capable of ionic charge conduction that has blocks for complexing or solvating a salt of an inorganic protonic acid, which is selected from the group consisting of polyether urea, polyether amide, polyether ester amide or polyether ester; and
(b3) a salt selected from the group consisting of LiClO4, LiCF3 SO3, NaClO4, LiBF4, NaBF4, KBF4, NaCF3 SO3, KClO4, KPF6, KCF3 SO3, KC4 F9 SO3, Ca(ClO4)2, Ca(PF6)2, Mg(ClO4)2, Mg(CF3 SO3)2, Zn(ClO4)2, Zn(PF6)2 or Ca(CF3 SO3)2, that has been complexed or solvated in the polymer or copolymer (b2).

Abstract
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 fibers, which mixture comprises (b1) an organic polymeric material that is fibrous or forms fibers 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 complexing or solvating a salt of an inorganic or low-molecular-weight organic protonic acid (b3) and has a better compatibility with the organic polymer (b1) that is fibrous or forms fibers on mixing than with the polymeric organic substrate (A); and (b3) a salt of an inorganic or low-molecular-weight organic protonic acid such as NaClO4 or K P F6 that has been complexed or solvated in the polymer or copolymer (b2). The invention relates also to the antistatic mixture (B) as such, to its use in rendering polymers antistatic and to a process for the preparation of antistatic thermoplastic or elastomeric polymeric substrates.
