Abstract
A polyphenylene ether molding composition which contains at least one alkylsulfonate as antistatic and at least one light stabilizer of the formula III ##STR1## has better antistatic properties and greater light stability than is the case for simultaneous use of alkylsulfonates and previously known light stabilizers, such as, for example, tetramethylpiperidinyl derivatives.
