发明名称 樹脂架橋粒子の製造方法
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a means furthermore improving an effect obtained by coupling agent processing (namely, bondable of more coupling agents to resin crosslinked particles), concerning amino resin crosslinked particles or phenol resin crosslinked particles. <P>SOLUTION: One embodiment of this invention for producing amino resin crosslinked particles includes processes of: obtaining a resin precursor by reacting an amino compound and/or a phenol compound with formaldehyde; and obtaining resin crosslinked particles by curing the resin precursor. The production method further includes a coupling agent treating process for mixing the resin crosslinked particles with coupling agents and heating them in the state where a methylol group rate of the resin crosslinked particles after curing is≥8%. <P>COPYRIGHT: (C)2012,JPO&INPIT</p>
