Stabilized polyacetal compositions |
| abstract |
Improvements in the thermal stability of polyacetal compositions containing microcrystalline cellulose or fibrous cellulose as melt processing stabilizers are achieved by the inclusion therein of a polyamide-based co-stabilizer or a meltable hydroxy-containing polymer or oligomer co-stabilizer, such as poly(ethylene vinyl alcohol). Improvements in the thermal stability of polyacetal compositions containing non-meltable polymer stabilizers containing formaldehyde reactive nitrogen or hydroxy groups and having an average particle size of less than 10 microns are achieved by the inclusion therein of at least one amide-containing phenolic antioxidant or alternatively, at least one meltable co-stabilizer compound, such as a conventional polyamide stabilizer, and a primary antioxidant. The compositions of the present invention are characterized as having excellent melt processing and long term thermal stability. |
