VERWENDUNG VON ALKALI- ODER ERDALKALISALZEN VON SULFOBERNSTEINSAEUREESTERN ALS INTERNE ANTISTATIKA, ABZIEH- UND WICKELHILFEN FUER TRANSPARENTE POLYCARBONATFOLIEN;SOWIE POLYCARBONATGIESSFOLIEN UND DEREN HERSTELLUNG.

摘要

Alkali(ne earth) salts of sulphosuccinate esters of formula (I), where M = an alkali metal cation and n = 1; or M = an alkaline earth metal cation and n = 2; R = 4-20C alkyl, 4-20C alkenyl, 6-20C cycloalkyl or 6-20C cycloalkenyl; are claimed for use as internal antistatics, take-off and winding aids for cast films of high mol., thermoplastic, aromatic polycarbonates (II), in amts. of 0.01-2 (wt.)% w.r.t. (I)+(II).
