Abstract:
A melt processable antistatic composition comprising:(a) an antistatic agent comprising a polymeric salt consisting of: (i) at least one cation represented by the formula: +N[(R1)4âˆ’y][[POA]R2]y where POA is either a homopolymer or a copolymer that is random, blocked, or alternating, and POA comprises 2 to 50 units represented by the formula ((CH2)mâ€²CH(R3)O) where each unit independently has mâ€² and R3,mâ€² is an integer from 1 to 4, R3 is independently hydrogen or a lower alkyl group, R1 is independently an alkyl, an alicyclic, an aryl, an alkalicyclic, an arylalicyclic, or an alicyclicaryl group that optionally contains one or more heteroatoms, R2 is independently hydrogen, an alkyl, an alicyclic, an aryl, an alkalicyclic, an arylalicyclic, or an alicyclicaryl group that optionally contains one or more heteroatoms, and y is an integer from 1 to 4; and (ii) a fluorinated anion represented by one of the following formulae: RfSO3âˆ’â€ƒâ€ƒ(1) âˆ’O3SRf2SO3âˆ’â€ƒâ€ƒ(2) where Rf is independently a perfluoroalkyl, fluoroalkyl, or fluoroaryl group having from 1 to about 12 carbon atoms; and Rf2 is independently a perfluoroalkylene, fluoroalkylene, or fluoroarylene group having from 1 to about 10 carbon atoms; and(b) at least one insulating material.
