Abstract
A polymer composition containing a physiologically active substance which can be released at a controlled rate is prepared by contacting one or more polymerizable monomers with the physiologically active substance, mking the monomers into a specific shape and then irradiating the shaped article with light or an ionizing radiation at a low temperature below room temperature to polymerize the polymerizable monomers.
