Abstract

Temperature-responsive polymers are a class of materials which undergo phase changes upon heating or cooling their solutions. A phase diagram for aqueous solutions of temperature-responsive polymers is characterized by so-called lower critical solution temperature (LCST). For a homopolymer, the final result of reaching the LCST is polymer phase separation in solution. In block copolymer solutions, however, the phase separation of one block can result in the formation of a self-assembled structure.

In this study we use small-angle neutron scattering (SANS), light scattering and NMR to study the formation of nanoparticles from temperature responsive PNIPAM-b-PEG-b-PNIPAM block copolymers, synthesised using atom-transfer radical polymerisation from a PEG macroinitiator.
