Abstract: | On the basis of macroinitiators of polyester type, hybrid comb-shaped polymers with poly-2-isopropyl-2-oxazoline side fragments are prepared via ring-opening cationic polymerization. A method for estimating the length of polyoxazoline side chains and their grafting density is proposed. It is shown that, at the given ratio of the length of backbone and side chains, which depends on the chemical structure of the initiator, the graft copolymers are capable of formation of micellar aqueous solutions with a lower critical solution temperature. |
