An X -ray method for studying the progress of the radiation-induced solid-state polymerization by the use of an internal crystalline standard has been presented. In this method, the absolute intensity of X -rays scattered by the crystalline phase of the polymerized substance is compared with that of X-rays scattered by the completely crystalline standard. As standards, crystalline organic substances, namely urotropine and adamantane, and as monomer — acrylamide have been used. This method can be applied to monomers with precisely known crystal structure. It permits the conversion of each polymerized sample to be determined without the necessity of deriving a calibration curve.
