Embodiment 1

[0074] Weigh 20g of diphenyl disulfide, Aerosil 200 (primary particle size: 12nm, specific surface area: 200±25m 2 / g) 0.2 g was put in an eggplant-shaped (pear-shaped) flask, and the evaporator was used to rotate and stir for 1 hour. The obtained sample was transferred to a 50 ml sample bottle and stored at 25°C. One week later, it was confirmed that diphenyl disulfide flowed without agglomeration when the sample bottle was placed horizontally.

Embodiment 2

[0076] Weigh 20 g of diphenyl disulfide and 0.02 g of Aerosil 200 into an eggplant-shaped (pear-shaped) flask, and rotate and stir for 1 hour using an evaporator. The obtained sample was transferred to a 50 ml sample bottle and stored at 25°C. One week later, it was confirmed that diphenyl disulfide flowed without agglomeration when the sample bottle was placed horizontally.

Embodiment 3

[0078] Weigh 20 g of diphenyl disulfide and 0.01 g of Aerosil 200 into an eggplant-shaped (pear-shaped) flask, and rotate and stir for 1 hour using an evaporator. The obtained sample was transferred to a 50 ml sample bottle and stored at 25°C. One week later, it was confirmed that when the sample bottle was placed horizontally, the diphenyl disulfide flowed, but it was partially agglomerated to form lumps. The force of disintegration of the block was measured by a compression tester, and it was confirmed that it was 0.26kg / cm 2 disintegrate.

Abstract

Provided is composition that is improved in terms of caking properties of a disulfide compound. Specifically provided is a composition that contains 0.01 parts by mass or more of an anticaking agent per 100 parts by mass of a disulfide compound represented by formula (1). (In the formula, R1 and R2 each independently represents a hydrogen atom, a C1-20 alkyl group, a hydroxy group, a C1-20 alkoxygroup, a substituted or unsubstituted amino group, a nitro group or a halogen atom.)

Description

technical field [0001] The present invention relates to compositions containing disulfide compounds and their anti-caking agents. Background technique [0002] It is well known that disulfide compounds improve the adhesion between metals and resins or improve the performance of resins when added to various resins. [0003] For example, it is reported that adding a disulfide compound in the production process of polyphenylene sulfide (hereinafter abbreviated as PPS) resin greatly reduces the sodium content and covalently bonded chlorine content in PPS resin (Patent Document 1) . [0004] In addition, it has been reported that by adding a disulfide compound to PPS resin, there are effects such as that even when melt-kneading is carried out at high energy, the change in viscosity can be reduced and the viscosity can be controlled, and the sulfur content can be obtained when heated. It is a molded article with little gas generation and good mechanical properties and good proce...
