Hyperbranched polymers from maleic anhydride, diethanolamine and ethylene glycol were syntheized by a two-step method, and radiation effects on intrinsic viscosity of the polymers were studied. The results showed that intrinsic viscosity of all the hyperbranched polymers irradiated in their bulk phase, unlike the irradiated polymers in their solution, decreased obviously, Discussions were made on mechanisms of viscosity decrease.
