STABILIZER COMPOSITION FOR ORGANIC POLYMER MATERIAL CONTAINING DIOXAPHOPHEPINE COMPOUND AND ORGANIC POLYMER MATERIAL COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain an organic polymer material composition having excellent processing stability and high heat-resistance by using a stabilizer composition as the stabilizer for the organic polymer material such as a synthetic resin. SOLUTION: The objective stabilizer composition for an organic polymer material contains (a) a 6-hydroxychroman compound, (b) a phosphorus-based antioxidant of general formula (2) and (c) a phenolic antioxidant. The content of the component (a) is 0.5-10 wt.% based on the sum of the components (a), (b) and (c). The organic polymer material composition is produced by adding the above stabilizer composition to an organic polymer.
