  The present invention pertains to a stabilizer composition for polymers comprising 1.5 - 23 % w/w of at least one polyol, 1.5 - 46 % w/w of at least one acid scavenger, 3.0 - 31 % w/w of at least one monomeric dihydrophyridine derivative selected from the group of substituted or unsubstituted dihydropyridine dicarboxylic acid esters, ester amides, and diamides, 0 - 5 % w/w of one or more oxidizing agents, and 0 - 94 % w/w of one or more additives, based on the total weight of the stabilizer composition, and wherein the stabilizer composition does not comprise any beta-diketone. The present invention finally pertains to a stabilized polymer composition containing this stabilizer composition, to a process for preparing the same, to the use thereof for the production of moulded articles, and to the resulting moulded articles.
