Abstract
The present invention relates to a stabilizer composition for organic polymer material containing (a) 6-hydroxychroman compound, a phosphorus antioxidant and (c) phenolic antioxidant, wherein the component (a) is contained in a proportion of 0.5 wt %-10 wt % and the total amount of the component (b) and the component (c) is in a proportion of 99.5 wt %-90 wt %, of the total amount of the components (a), (b) and (c). The present invention also relates to an organic polymer material composition containing an organic polymer and the above-mentioned stabilizer composition for organic polymer material. The use of the stabilizer composition of the present invention as a stabilizer for organic polymer materials affords an industrially extremely useful stabilized organic polymer material composition superior in heat stability during processing.
