Abstract
A polyarylene sulfide resin composition contains a polyarylene sulfide containing at least one group selected from a group consisting of an amino group and an amide group, a polyamide resin, an epoxy resin and, as needed, a filler. A further composition contains 100 parts by weight of the polyarylene sulfide, 0.05 to 5 parts of the epoxy resin, and 5 to 400 parts of the filler. Another type of the resin composition contains the polyarylene sulfide, the polyamide, a compound selected from an acid, an acid anhydride and an acid halide, each having in its molecule not less than two functional groups reactive with the amino group or the amide group, and, as needed, the filler. A further type of the resin composition contains the polyarylene sulfide, the compound and, as needed, an inorganic filler subjected to surface treatment with a silane type coupling agent. A still further type of the resin composition contains the polyarylene sulfide and the compound. A still further type of the resin composition contains the polyarylene sulfide and the inorganic filler subjected to surface treatment with an epoxysilane type coupling agent.
