About 0.001 to 5 parts by weight of a hindered phenol-series compound, about 0.01 to 5 parts by weight of a weather (light)-resistant stabilizer, and about 0.001 to 10 parts by weight of a spiro-compound having a triazine ring are added to 100 parts by weight of a polyacetal resin. The spiro-compound may be a compound represented by the following formula (1). The polyacetal resin composition may further comprise a coloring agent, a processing stabilizer, a heat stabilizer, and others.
wherein R1 and R2 are the same or different, each representing an alkylene group, an arylene group, or an aralkylene group.
A polymeric composition containing a polyacetal resin in conjunction with a formaldehyde inhibiting agent is described. The formaldehyde inhibiting agent comprises an aluminum pigment. The aluminum pigment may comprise elemental aluminum, such as aluminum flakes that cannot only drastically reduce formaldehyde emissions from the composition but can also give the composition a metallic appearance. In one embodiment, the aluminum pigment may be combined with the polyacetal resin in conjunction with an unhindered phenol and/or a polyethylene resin. In order to further reduce formaldehyde emissions, in one embodiment, a formaldehyde scavenger comprising a nitrogen containing compound can also be added.

A polymeric composition containing a polyacetal resin in conjunction with a blend of metal salts for reducing formaldehyde emissions. In one embodiment, the blend of metal salts comprises a metal salt of a fatty acid blended with a metal salt of a polycarboxylic acid. The metal salt of the fatty acid may comprise calcium propionate, while the metal salt of the polycarboxylic acid may comprise calcium citrate. The metal salts have been found to reduce formaldehyde emissions, especially when the composition contains a low gloss additive, such as acrylic polymer particles.
