This invention relates to a polymer composition comprising (a) high-density polyethylene (HDPE), polyamide 11, polyamide 12 (PA 11, PA 12), a natural or synthetic elastomeric polymer or copolymer or a natural or synthetic elastic vulcanisate, (b) a polyoxyalkylene of formula R1-O-[CH(R3)-CH2-O-]n-[CH2-[CH(OH)]p-CH2-O]q-[C(O)]r-R2 (I), wherein R1 is H, C1-C24alkyl, C2-C24alkenyl, CH2=CH-C(O) or CH2=CCH3-C(O), R2 is C1-C24alkyl, C2-C24alkenyl, CH2-COOH, or N(C1-C20alkyl)2, R3 is H or CH3, n is a number higher than or equal to 2, p is a number from 1 to 6, and q and r are independently of each other 0 or 1; and (c) a salt of formula {MZ+ a A(az/b)-b}, wherein M is a z-valent alkali metal cation, alkaline earth metal cation or zinc cation,a and b are independently of each other a number from 1 to 6, and A is an anion of an inorganic protonic acid or of an organic mono- or polycarboxylic acid. This polymer composition has excellent antistatic properties. |
