Abstract

PURPOSE:To prepare microcapsules with shells high in mechanical strength in which enveloped core material is fixed excellently, by impregnating microcapsule base material, which is formed from a photocrosslinkable high molecular cpd. as shell and does not envelope core material, with core material soln., then irradiating the base material with light. CONSTITUTION:A photocrosslinkable high molecular cpd. is made by introducing a hydrophobic photosensible group (e.g., cinnamoyl group) to a hydrophilic high molecular cpd. such as PVA. The high molecular cpd. is then dissolved into an org. solvent (e.g., CHCl3) to form 0.01-10 wt.% soln. To the soln. is added water or aq. solvent and is stirred violently so as to be emulsified. Microcapsules diposited at the interface between the dispersion medium and the liq. drops, and enveloping solvent inside are separated. The microcapsules are impregnated with a core material (e.g., enzime, pharmaceuticals) soln. in order to make the core material infiltrate through shells into inside. The microcapsules enveloping the core material is irradiated with light in order to photo crosslink the high molecular cpd., which constitutes the shells through the photo-crosslinkable group.
