Incorporation into polyacetal molding compositions stabilized for processing with a non-meltable polymer stabilizer of 0.01-1.00 weight percent of at least one meltable co-stabilizer, said co-stabilizer being a thermal stabilizer for polyacetal, and 0.02-1.0 weight percent of at least one primary antioxidant results in significantly improved long term stability, as evidenced by greater retention of physical properties over time, of such compositions.
