发明名称 PROCESS FOR PREPARING FREE-FLOWING ETHYLCELLULOSE MICROCAPSULES
摘要 <p>A process for preparing free-flowing microcapsules by taking advantage of the phase-separation of ethylcellulose in cyclohexane is disclosed. In this process, a hydrocarbon compound which is soluble in cyclohexane and have a molecular weight of 150 to 3,000 and a solubility parameter ( delta , at 25 DEG C.) of 7 to 10 (cal/cm3)1/2 is used as the phase-separation-inducing agent.</p>
