Preparation of Polymeric Hollow Microspheres.

KAGAKU KOGAKU RONBUNSHU, 1997
Polymeric hollow microspheres of a few ten μm in diameter were prepared by removal of the encapsulated solution from polymeric microcapsules by in situ polymerization. As a result, no rupture of microcapsules occured and a high yield of polymeric hollow microspheres was obtained under the condition of lower ratio of the encapsulated solution to monomer
