[0253]

[0254] Using polyarylene sulfide (A-1) as component (a), polyarylene sulfide (B-1) as component (b), and fibrous filler (F-1) as component (f), The polyarylene sulfide resin compositions of Examples 1-4 and Comparative Examples 1-4 were produced. When producing the PAS resin composition of each example and comparative example, (a) component, (b) component and (f) component were supplied to the Japan Steel Works Co. A TEX30α-type twin-screw extruder (L / D=45.5, 5 kneading sections) was produced. Specifically, the components (a) and (b) are supplied (main feed) from the main feeder of the extruder (distance L / D = 45.5 from the die), and the component (f) is supplied from the distance from the die At L / D=15, it is supplied from the middle using a side feeder (side feed). Moreover, when using both (a) component and (b) component, both are dry-blended before main feeding. Using the above-mentioned extruder, the screw speed was 300 rpm, the barrel temperature was set so...

Abstract

The subject of the present invention relates to the production of reactive functional group-containing polyarylene sulfide having a narrow degree of dispersion and a small amount of gas generation by mixing polyarylene sulfide resin (a) and polyarylene sulfide resin (b) A resin composition in which the polyarylene sulfide resin (a) has a weight loss rate ΔWr of 0.18% or less upon heating, and when a reactive compound (c) having a reactive group is added, relative to Before the reactive compound (c) is added, the melt viscosity increase rate is less than 1.05 times, the weight loss rate ΔWr of the polyarylene sulfide resin (b) when heated is 0.18% or less, and after adding the reactive compound In the case of the reactive compound (c), the increase rate of the melt viscosity is 1.05 times or more relative to that before the addition of the reactive compound (c).

Description

technical field [0001] The present invention relates to a polyarylene sulfide resin composition having a reactive functional group, a small amount of gas generation, and a narrow molecular weight distribution, a method for producing the same, and a molded article thereof. Background technique [0002] Polyarylene sulfide (hereinafter, sometimes abbreviated as PAS) represented by polyphenylene sulfide (hereinafter, sometimes abbreviated as PPS) has excellent heat resistance, barrier properties, chemical resistance, electrical insulation, and heat and humidity resistance. A resin with properties suitable for engineering plastics, such as chemical properties and flame retardancy. In addition, it can be molded into various molded parts, films, sheets, and fibers by injection molding or extrusion molding, and is widely used in various electrical and electronic parts, mechanical parts, and automotive parts that require heat resistance and chemical resistance. field. [0003] As ...
