Polymer composition containing a physiologically active substance
First Claim
1. A process for preparing a polymer composition containing a physiologically active substance which is released at a controlled rate, said process comprising contacting 10 parts, by weight, of at least one polymerizable monomer and 0.1 to 3 parts, by weight, of at least one physiologically active substance and irradiating them with light or an ionizing radiation while maintaining the system in an anhydrous condition and in an airless state such that in the produced polymer composition the physiologically active substance is capable of being released at a controlled rate.

Abstract
A polymer composition containing a physiologically active substance and being capable of releasing it at a controlled rate can be prepared by contacting 10 parts, by weight, of one or more polymerizable monomers and 0.1 to 30 parts, by weight, of one or more physiologically active substances and irradiating them with light or an ionizing radiation while maintaining the system in an anhydrous condition and in airless state.
