Graft copolymers of Polyacrylamide‐g‐Dextran were synthesized using ceric‐ion‐initiated solution polymerisation technique. It is shown that the macromolecular parameters of these copolymers and their molecular structure strongly depend on the molecular weight of the Dextran part.

Conformational changes have been studied in intramolecular polymer‐polymer complexes (intraPC) of graft copolymers of poly(acrylamide) and poly(vinyl alcohol) (PVA‐g‐PAA) with various numbers of grafts (4‐42) per molecule as a function of temperature and copolymer concentration. It is shown that the magnitude of conformational change depends on the grafts content while the temperature range over which the conformation changes occur is essentially determined by copolymer concentration. The conformational changes are reversible on heating and cooling.
