Abstract

Liquids are encapsulated by an interfacial condensation or addition polymerization reaction by forming a dispersion of the liquid to be encapsulated in another liquid immiscible therewith and causing a reaction to occur between reactants, at least one of which is dissolved in the dispersed phase, and at least one of which is dissolved in the continuous phase after the formation of the dispersion. At least one of the said reactants is a polyfunctional reactant or a difunctional reactant having dissolved with it a polyfunctional re actant. Particular reference is made to reactions involving the formation of polyamides, polyesters, polyureas, polycarbonates and polyurethanes by conventional reactions. Specific examples relate to the reaction of (a) sebacoyl chloride and trimesoyl chloride with ethylene diamine and 1,3,5-benzene triamine, or (b) with pyrogallol; (c) phosgene with 1,3,5-benzene triamine and ethylene diamine, or (d) with bisphenol A and pyrogallol, (e) ethylene bischloroformate with bisphenol A and phloroglucinol, (f) toluene-2,4-diisocyanate and trimesoyl chloride with ethylene diamine and diethylene triamine, (g) azelaoyl chloride and polymethylene isocyanate with diethylene triamine.
