Interference No. 103,029
Count 1
An antistatic thermoplastic composition comprising:
(A) 80% or more by weight of a copolymer having a
rubber substrate and a rigid phase, said rigid phase including
an acrylonitrile and a vinyl aromatic compound and being
substantially free of non-nitrilated acrylic compounds; and
(B) 20% or less by weight of an epihalohydrin
copolymer of an epihalohydrin and an oxirane-containing
comonomer, wherein the ratio by weight of said epihalohydrin
to said oxirane comonomer is equal to or less than 1:1;
wherein said epihalohydrin copolymer is present in an amount
such that said antistatic thermoplastic composition has
improved antistatic properties in comparison to said
antistatic thermo- plastic composition wherein said
epihalohydrin copolymer is absent.
