Abstract
In this work we examined the formation of polymeric material from the radiation-induced reactions of aqueous formaldehyde. The polymers obta ined by this procedure are very different from those formed by thermal or UV polymerization. Two polymeric materials precipitated between 0. 8 and 1.3 MGy. Although these polymers have the same chemical composit ion (C2H3O), infrared spectrum, and NMR spectrum, they differ in densi ty, color and melting point. The interconversion of the polymeric mate rials increase when the dose is raised.
