Abstract
The invention relates to a composition comprising a thermoplastic, structurally crosslinked elastomeric or thermosetting polymer, which comprises PA1 (a) a polar, adsorptive inorganic or organic material in the form of fibres or particles which are in mutual contact, onto which is adsorptively bound PA1 (b) a polar antistatic agent comprising a mixture of PA2 b1) at least one polar organic compound having at least 5 carbon atoms and at least 3 heteroatoms, and PA2 b2) the salt of an inorganic protic acid, which is solvated or complexed in the polar organic compound. The invention also relates to a second composition comprising b) a polar inorganic or organic material, b1) a polar organic compound having at least 5 carbon atoms and at least 3 heteroatoms and b2) an inorganic salt, to the use of this second composition for the antistatic treatment of polymers, and to a process for preparing antistatically treated polymers.
