HEAT ACCUMULATING MICROCAPSULE

摘要

PROBLEM TO BE SOLVED: To prepare a heat accumulating microcapsule which has an excellent processibility compared to that of the conventional heat accumulating microcapsules and may be used for general purposes. SOLUTION: This heat accumulating microcapsule is prepared by forming at least one layer of a capsule wall essentially comprising a thermoplastic resin obtained through radical polymerization around a core material essentially comprising a compound allowing free phase transition. Here, the average particle size of the microcapsule is from 10 to 3,000 μm.
