MICROENCAPSULATION BY INTERFACIAL POLYMERIZATION OF A POLYAMINE AND A POLYBASIC ACID CHLORIDE OR ANHYDRIDE

摘要

- 14 -A B S T R A C TMICROENCAPSULATION PROCESSIn a microencapsulation process involving aninterfacial polymerization reaction between a compoundcontaining amine groups and a polybasic acid chlorideor anhydride, the polymerization being carried out inan emulsion of an aqueous solution in a hydrophobicorganic liquid, the reaction is terminated by introduc-ing water into the hydrophobic phase of the emulsionwhere it reacts with and destroys the residual acidchloride or anhydride.
