<P>PROBLEM TO BE SOLVED: To provide a polyacetal resin composition which exhibits excellent rigidity (mechanical property) and appearance when formed into a molded article and produces less formaldehyde, and a method for producing the same. <P>SOLUTION: The polyacetal resin composition contains, per 100 pts.wt. of (a) a polyacetal resin, 10-150 pts.wt. of (b) a woody fine powder containing 5-35 wt.% of lignin and having ≤3 wt.% of sieve residue remaining on the sleeve when sieved by a sieve with an opening of 250 μm, 0.01-3 pts.wt. of (c) a hindered phenol antioxidant, 0.01-3 pts.wt. of (d) at least one nitrogen-containing compound that is selected from among aminotriazine compounds, guanamine compounds, hydrazide compounds and polyamides, and 0.01-3 pts.wt. of (e) at least one processing aid that is selected from among long-chain fatty acids, long-chain fatty acid derivatives, polyoxyalkylene glycols and silicone compounds. <P>COPYRIGHT: (C)2013,JPO&INPIT |
