Abstract
A reactive functional group-containing polyarylene sulfide resin composition having a narrow polydispersity and a low gas generation amount is manufactured by mixing a polyarylene sulfide resin (a) and a polyarylene sulfide resin (b), wherein the polyarylene sulfide (a) has a weight reduction ratio ΔWr of not higher than 0.18% under heating and an increase rate of melt viscosity of less than 1.05 times by addition of a reactive compound (c) having a reactive group relative to melt viscosity prior to addition of the reactive compound (c), and the polyarylene sulfide (b) has the weight reduction ratio ΔWr of not higher than 0.18% under heating and the increase rate of melt viscosity of not less than 1.05 times by addition of the reactive compound (c) having the reactive group relative to melt viscosity prior to addition of the reactive compound (c).
