Abstract

1,075,952. Microcapsules. GELATINE & GLUE RESEARCH ASSOCIATION. Dec. 31, 1963 [Dec. 31, 1962; Oct. 10, 1963], Nos. 49183/62 and 40096/63. Heading B8C. Microcapsules are formed by causing to coacervate around a nucleus from aqueous solution, a material which contains not less than <SP>1</SP>/ 3 by weight of a polymeric amine which has been chemically modified to render it sufficiently hydrophobic to coacervate from aqueous solution by adjustment of pH. Suitable amines are zein, casein, albumin, soya beam protein, collagen glues, gelatine and peptides derived from these proteins which have been reacted with various organic sulphonyl chlorides, 2,4. dinitro-1-fluoro-benzene, phenyl isothiocyanate, benzoyl chloride, halogeno-s-triazine derivatives, halogeno pyrimidyl derivatives and ninhydrin. Preferably, reactive groups are introduced into the molecule by the reaction whereby cross-linking can occur either during or after coacervation so that hardened capsules are produced.
