Zusammenfassung:	PROBLEM TO BE SOLVED: To provide processes for continuously coalescing particles from an aggregated particle slurry.SOLUTION: The aggregated particle slurry is heated, and then coalesced by raising the pH. The coalesced particles are homogenized and exit as a coalesced particle slurry. A multi-screw extruder is used for the coalescing. These processes are useful for providing coalesced particles such as toner compositions. 【課題】凝集した粒子スラリーから粒子を連続的に融着させるためのプロセスを提供する。【解決手段】凝集した粒子スラリーを加熱し、次いで、ｐＨを上げることによって融着させる。融着した粒子を均質化し、融着した粒子スラリーとして出す。マルチスクリュー押出機を融着に使用する。これらのプロセスは、トナー組成物のような融着した粒子を提供するのに有用である。【選択図】なし
