ABSTRACT OF THE DISCLOSURE This invention relates to a process for preparing a polymer composition containing a physiologically active substance. The process is characterized by contacting one or more polymer- izable monomers and the physiologically active substance, forming them into a specific shape and irradiating the shape with light or an ionizing radiation at a low temperature below room temperature to polymerize the polymerizable monomers. The polymer is a highly desirable material for use as a supporting carrier and allows for the release of the active substance in a controlled manner. The process of this invention allows the active substance to be carried in the carrier in a uniform amount and to be released therefrom at an appropriate rate. The structure of the polymer is such to allow for this release and the active substance may be carried by the polymer at a low temperature to prevent un- desirable side-effects.
