ABSTRACT OF THE DISCLOSURE Capsule-shaped polymer particles and a process for the production thereof are described. In one embodiment of the process, a polymerizable monomer component containing a cross-linkable monomer and a hydrophilic monomer, and an oily substance are finely dispersed in water to pre- pare an oil-in-water emulsion and then the polymerizable monomer component is polymerized, whereupon capsule- shaped polymer particles containing the oily substance as a core material are obtained. Upon removal of the oily substance from the particles, there are obtained capsule- shaped hollow polymer particles. These capsule-shaped polymer particles are excellent in such properties as mechanical strength and heat resistance, and thus can find many applications.
