Abstract
Polymer compositions comprising a) a polymer substrate selected from the group consisting of the polyolefins, polyesters, polyamides and polylactic acids and b) a combination of i) at least one permanent antistatic additive selected from the group consisting of the polyetheresteramides and ii) at least one migratory antistatic additive selected from the group consisting of the alkylsulfonic acid salts, the alkyl diethanolamines and the alkyl diethanolamides, are effectively antistatic.
Claims19
An antistatic polymer composition comprising
- a) a polymer substrate selected from the group consisting of polyolefins, polyesters, polyamides and polylactic acids and
- b) a combination of
- i) at least one permanent antistatic additive selected from the group consisting of polyetheresteramides and
- ii) at least one migratory antistatic additive selected from the group consisting of straight or branched chain alkyl diethanolamides.
An antistatic additive mixture comprising
- i) at least one permanent antistatic additive selected from the group consisting of polyetheresteramides and
- ii) at least one migratory antistatic additive selected from the group consisting of straight or branched chain alkyl diethanolamides.
A process for the preparation of antistatically finished polymers selected from the group consisting of polyolefins, polyesters, polyamides and polylactic acids,
- which process comprises mixing an additive mixture comprising
- i) at least one permanent antistatic additive selected from the group consisting of polyetheresteramides and
- ii) at least one migratory antistatic additive selected from the group consisting of straight or branched chain alkyl diethanolamides,
- as such or in the form of its individual components and together with optional further additives with said polymers in calenders, mixers, kneaders or extruders.
