Polypropylene ionomer composition with antistatic and/or non-dew forming properties and films thereof

摘要

A polypropylene composition (PPC) with permanent antistatic and/or non-dew-forming properties containing (a) random copolymer and/or terpolymer polypropylene(s) and (b) a hydrophilic polyether-polyamide block copolymer, in which the polypropylene components (a) contain at least one unsaturated carboxylic acid compound (c). Independent claims are also included for (1) a method for the production of PPC by mixing the components in a compounder, melting at 180-240[deg]C, cooling in a water bath and then granulating (2) film with permanent antistatic and non-dew-forming properties made from PPC .
