PROBLEM TO BE SOLVED: To provide a polyacetal resin composition which has extremely high weather (light) resistance and suppresses the generation of a volatile organic compound (VOC) from a molded product, particularly the generation amount of formaldehyde, at a low level. ! SOLUTION: There is provided a polyacetal resin composition which comprises: (A) a polyacetal copolymer having 1.0 mmol/kg or less of a hemiformal terminal group, 2.0 mmol/kg or less of a formyl terminal group and 0.5 wt.% or less of an unstable terminal group; (B) an N-substituted melamine compound represented by the following general formula (I); (C) a hindered amine-based stabilizer; (D) an ultraviolet ray absorber; and (E) a hindered phenol-based antioxidant. In the following general formula (I), R is an aliphatic hydrocarbon group having 5 to 10 carbon atoms. ! COPYRIGHT: (C)2015,JPO&INPIT |
