組成物に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to aqueous suspension compositions of solid organic peroxides. More specifically, in order to obtain a long-term stable aqueous suspension composition without the need for a special dispersion machine,
The present invention relates to an aqueous suspension composition containing an organic peroxide having a specific gravity of 1 or more and at least one neutral inorganic salt.

る。Among organic peroxides, solid organic peroxides have excellent storage stability, but they are difficult to handle due to their lack of fluidity and are unstable against mechanical shock. (written as BPO) are hydrothermal body products and DOP.
Although it is commercially available as a paste product, in recent years, automatic loading of catalysts has been studied in polymerization plants, and solid organic peroxides have been developed into aqueous suspensions that are fluid and stable enough to be pumped. Development of a suspension liquid is desired.

物を得ることが出来た。In particular, for dilauroyl peroxide, didecyl peroxydicarbonate, di-t-butyl peroxy isophthalate, etc., an aqueous mixture consisting of a protective colloid is pulverized and suspended in a pulverizer such as a ball mill, hammer mill, or mill. A method of suspending the particles using an ultrasonic homogenizer or an ultrasonic homogenizer has been exemplified, but these methods have problems such as precipitation of particles and creaming. Furthermore, aromatic diacyl peroxides such as BPO may be decomposed by mechanical impact, so it is difficult to say that atomization using a pulverizer or the like is effective. According to the present invention, it was possible to obtain an aqueous 12 composition that was stable for one month or more without particularly pulverizing the organic peroxide using a pulverizer or the like.

組成物か得られたものである。To explain the present invention in more detail, in order to obtain an aqueous suspension of an organic peroxide such as BPO, which has a specific gravity of 1.33 and is heavier than water, the specific gravity of water is increased by adding a water-soluble neutral inorganic salt. is made equal to the specific gravity of the organic peroxide, and a stable aqueous suspension composition is obtained in which the organic peroxide does not settle and separate even if left for a long period of time.
