[0101] (Examples 1 to 100) The synthetic resins and compounds containing a group represented by general formula (1) shown in Tables 1-10 were blended in the amounts shown in Tables 1-10, along with 0.05 parts by mass of a phenolic antioxidant (tetrakis[methylene-3-(3',5'-tert-butyl-4'-hydroxyphenyl)propionate]methane) and 0.1 parts by mass of a phosphorus-based antioxidant (tris(2,4-di-tert-butylphenyl)phosphite), and then mixed for 1 minute at a rotation speed of 1000 rpm using an FM mixer (FM200, manufactured by Mitsui Mining Co., Ltd.). The resulting mixture was melt-kneaded using a twin-screw extruder (TEX-28V, manufactured by The Japan Steel Works, Ltd.) at a resin temperature of 230°C and a screw speed of 150 rpm, and then granulated to obtain pelletized resin compositions. In Tables 1-10, the blend amounts are expressed in parts by mass. The resin compositions of Examples 1 to 100 obtained as described above had superior properties compared to control samples obtained under the same conditions as the respective Examples except that they did not contain a compound containing a group represented by general formula (1).
