An antistatic polymeric composition consisting of at least one antistatic additive of an ethylene oxide copolymer in the range of from about 3 to about 30% by weight and being a solid, nonionic material and having a dilution solution viscosity of greater than 0.25 and preferably having an average molecular weight greater than 20,000; and a polymeric material in the range from about 70 to about 97% by weight. The ethylene oxide copolymer comprises ethylene oxide in the range of from about 5 to about 95% by weight and at least 1 comonomer selected the group consisting of cyclic ethers, cyclic acetals, and cyclic esters, in the range of from about 95 to about 5% by weight. The polymeric material can be any thermoplastic, thermoplastic elastomer, or elastomer including ABS, ASA, polyamides, PBT, PET, PETG, PMMA, PUR, PVC, CPVC, PC, POM, POP, SMA, and SAN.
