- 0.0001 to 5.0 parts by weight, relative to 100 parts by weight of the polyacetal resin, of at least one monoamide compound represented by the following formula (2): ##STR13## wherein R.sup.6 represents a C.sub.1 -C.sub.30 alkyl group or a C.sub.2 -C.sub.30 alkenyl group, and R.sup.7 represents a C.sub.2 -C.sub.10 alkylene group, a C.sub.2 -C.sub.10 alkenylene group, or a group represented by formula --R.sup.8 --Ph--R.sup.9 --, wherein each of R.sup.8 and R.sup.9 independently represents a single bond or a methylene group, and Ph represents a phenylene group.
- 2. The resin composition according to claim 1, which further comprises 0.01 to 5.0 parts by weight, relative to 100 parts by weight of said polyacetal resin, of at least one hindered phenol compound.
- 3. The resin composition according to claim 1, which further comprises 0.01 to 5.0 parts by weight, relative to 100 parts by weight of said polyacetal resin, of at least one hindered amine compound.
- 4. The resin composition according to claim 1, which further comprises 0.01 to 5.0 parts by weight, relative to 100 parts by weight of said polyacetal resin, of at least one compound selected from the group consisting of benzotriazole compounds and oxalic anilide compounds.
- 5. The resin composition according to claim 4, which further comprises 0.01 to 3.0 parts by weight, relative to 100 parts by weight of said polyacetal resin, of at least one polyalkylene glycol represented by the following formula (3):
- R.sup.10 --O--(R.sup.11 --O).sub.n --(R.sup.12 --O).sub.m --O--R.sup.13( 3)
- wherein each of R.sup.10 and R.sup.13 independently represents a hydrogen atom, a C.sub.1 -C.sub.30 alkyl group, a C.sub.2 -C.sub.30 alkenyl group, a C.sub.1 -C.sub.30 acyl group or a C.sub.7 -C.sub.30 alkylphenyl group, each of R.sup.11 and R.sup.12 independently represents a C.sub.2 -C.sub.6 alkylene group, and each of n and m independently represents an integer of 1 or more with the proviso that n+m<1,000.
- 6. An insert molded article comprising a polyacetal resin composition according to claim 1 and a shaped part unified with said resin composition by insert molding.
