摘要：

The graft copolymers of Polyacrylamide (PAA) to Dextran (M-w = 20000 and Mw = 70000) have been synthesised by ceric-ion-reduced redox initiation method. Molecular characteristic of graft copolymers were determined from light scattering, SEC, and viscometry data. it was established that the increase of molecular weight of Dextran component up to 3.5 times do not influence essentially organization at molecular level of these copolymers in aqueous solution. Thet D-g-PAA copolymers capable of binding the heavy metal ions.
