preparation example

[0075] Preparation example: preparation of PPS

[0076]In a 5 L reactor equipped with a thermocouple for measuring the internal temperature of the reactor and a vacuum line for filling nitrogen and creating a vacuum, a mixture containing 5,130 g of p-diiodobenzene (p-DIB) and 450 g of sulfur was heated to 180°C to completely melt and mix. By initiating the reaction at 220 °C and 350 Torr, and gradually increasing the temperature and reducing the pressure for 4 hours to the final conditions of 300 °C and 0.6-0.9 Torr, and by injecting 7 times of sulfur and 19 g each, the mixed The reactants undergo a polymerization reaction. When the polymerization reaction has progressed to about 80% (the extent of the polymerization reaction is determined by "(current viscosity / target viscosity)×100"), that is, the relative ratio of the current viscosity to the target viscosity. The current viscosity was measured by taking a sample during the polymerization, and the target viscosity was s...

Abstract

The present invention relates to a polyarylene sulfide composition having a low out-gas content, and having excellent brightness, acid resistance and adhesion to metals. The polyarylene sulfide resincomposition of the present invention exhibits excellent brightness, acid resistance and metal adhesive strength as well as a low out-gas content, and thus can be useful as a resin composition for manufacturing a product requiring molding precision.

Description

technical field [0001] The present invention relates to a polyarylene sulfide composition having a small amount of outgassing and excellent whiteness, acid resistance and metal adhesion. Background technique [0002] At present, polyarylene sulfide (hereinafter referred to as "PAS"), as a typical engineering plastic, is used in high temperature and corrosive environments due to its high heat resistance, chemical resistance, flame retardancy and electrical insulation There is a growing demand in products and various electronic goods. Polyphenylene sulfide (hereinafter referred to as "PPS") is the only commercially available polyarylene sulfide. PPS is widely used in housings or main parts of automotive equipment, electrical or electronic equipment because of its excellent mechanical, electrical, thermal properties and chemical resistance. [0003] A method widely used in the commercial production of PPS is solution polymerization of p-dichlorobenzene (hereinafter referred t...
