POLYACETAL RESIN COMPOSITION AND MOLDINGS
Document Type and Number:
WIPO Patent Application WO/1998/029510
Kind Code:
A1
Abstract:
A polyacetal resin composition prepared by adding about 0.01 to 10 parts by weight of a glyoxydiureide compound to 100 parts by weight of a polyacetal resin. The glyoxydiureide compounds usable herein include glyoxydiureide itself and derivatives thereof (such as metal salts thereof). About 0.01 to 10 parts by weight of a basic nitrogen compound may be further added thereto. The nitrogen compounds usable herein include melamine, melamine resins, and polyamide resins. In addition, an antioxidant may be added to the composition. The compositions serve to improve the stability, particularly the thermal stability, of the polyacetal resin, and prevents the evolution of formaldehyde.
