Behaviorial Features of Aqueous Solutions of Thermoresponsive and pH-Sensitive Polymers with complicated architectures

Research on self-organization and aggregation in solutions of thermoresponsive and pH-sensitive polymers with complicated architectures such as star-shaped polyoxazolines and grafted copolymers with a polyimide spine and polydimethylaminoethylmethacrylate side chains was reviewed. A statistical N-isopropylacrylamide—maleic-acid copolymer was studied for comparison. Hydrophobic blocks in the macromolecules reduced the phase-stratification temperature and changed the set of scattering species by forming monomolecular micelles. An increased intramolecular density led to slower aggregate formation in solutions of polymers with complicated architectures.
