Abstract

In order to obtain the fundamental information required to prepare microcapsules by interfacial polycondensation polymerization, emulsions were made by dispersing limonene oil in the aqueous solution of PVA with different degrees of saponification. The microcapsule was made by polycondensation reaction between isocyanate and amine. We investigated growth speed of the microcapsule wall in polycondensation. And we considered how PVA species with different degree of saponification affected the shell growth of microcapsules.
