Production method and granule condition carboxyl group content polymer particle of granule condition carboxyl group content polymer particle

摘要

As for this invention, bulk density is large, at the same time designates that the method of producing the granule condition carboxyl group content polymer particle which swelling it is easy to do simply is offered as purpose in the water.As for this invention, process and the aforementioned carboxyl group content polymer particle which produce the carboxyl group content polymer particle way containing liquid ratio 5 - 25 mass % with it becomes, the sucking/absorbing liquid after drying the cohesion body of process, and the aforementioned carboxyl group content polymer particle which produce the cohesion body of the aforementioned carboxyl group content polymer particle by the thing which it can point the polarity organic solvent, the process which pulverizes, it is production method of the granule condition carboxyl group content polymer particle which features that it possesses.
