PURPOSE:To provide a plastic which is readily biodegradable and from which a small-sized molding of a complicated shape can be obtained. CONSTITUTION:Fine particles 2 of a biodegradable polymer, e.g. a natural polymer, are allowed to adhere to the surface of each of particles 1 of a microbiologically stable polymer, thereby to encapsulate each of the particles 1. A powder of the resulting microcapsules 3 is molded into a predetermined shape by, e.g. hot pressing. |
