Electrostatic dissipating polymeric material comprising ethylene oxide copolymer as an impact modifying agent.

摘要

The present invention is directed to a high impact electrostatic dissipating material having exceptional weathering ability comprising a first polymer having a glass transition temperature greater than 25 DEG C and a second polymer comprising ethylene oxide copolymer, wherein the GPC molecular weight relative to polystyrene of the second polymer is less than about 200,000 and about 10 to 25 parts by weight of the second polymer are present in the material based upon 100 weight parts of the first polymer. In a preferred embodiment of the present invention, the second polymer is an ethylene oxide and epichlorohydrin copolymer having a weight ratio of less than about 80 parts ethylene oxide to greater than about 20 parts epichlorohydrin, wherein the GPC molecular weight relative to polystyrene of the second polymer is less than about 1,000,000.
