Abstract
Abstract A stabilizing composition consisting of substituted alpha- or beta-naphthindoles, benzoylated or not benzoylated, and combined with organic polyimines such as those of formula 1 of the formulae sheet, in which R is alkyl or dialkyl, ethoxylated alkylmercaptans with 2∝8 ethoxy groups and (metal) halides of barium, calcium, lithium, zinc or aluminum, have a strong thermostabilizing effect on chlorine containing thermoplastics, especially on polyvinyl chloride, both homo-M and S polymers thereof, and on polyvinylidene chloride.
