Title:

POLYARYLENE SULFIDE RESIN COMPOSITION AND MOLDED ARTICLE COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2015/098748

Kind Code:

A1

Abstract:

　A polyarylene sulfide resin composition obtained by combining 0.001-10 mol% of (B) an organic carboxylic acid alkaline earth metal salt with respect to the formula –(Ar-S)-, which is a repeating unit of polyarylene sulfide, with respect to (A) polyarylene sulfide, wherein the weight-average molecular weight of the (A) polyarylene sulfide is 10,000 or higher and the weight loss on heating of the polyarylene sulfide resin composition satisfies the following formula. ΔWr = (W1 - W2)/W1 × 100 ≦ 0.18(%) (where ΔWr is the weight loss rate (%), which is a value determined from the sample weight upon reaching 330°C (W2) with respect to the sample weight upon reaching 100°C (W1) when thermogravimetric analysis is conducted at a heating rate of 20°C/min from 50°C to any temperature of 330°C or above in a normal-pressure non-oxidizing atmosphere). Provided is a polyarylene sulfide resin composition having a lowered crystallization temperature, suppressed solidification rate, and low gas generation under high temperature, using polyarylene sulfide obtained by a simple, economical method.
