ABSTRACT:
Incorporation into polyacetal molding compositions stabilized with a non-meltable polymer stabilizer of 0.02-1.0 weight percent of at least one amide-containing phenolic antioxidant results in significantly improved long term stability, as evidenced by greater retention of physical properties over time, of such compositions.
