Self-Assembly Processes in Aqueous Solutions of Heatsensitive Linear Copolymers Derived from N(Dimethylamino)Ethyl Methacrylate

Resumo

Light scattering and turbidimetry were used to study self assembly processes of macromolecules of a linear copolymer derived from 2(dimethylamino)ethyl methacrylate in aqueous solution. A sample with molecular mass 24,000 g/mole was studied. A structural phase transition is observed with increasing temperature in solutions of this copolymer. The temperatures for the onset and completion of phase separation as well as the width of this interval increase with decreasing concentration of the copolymer in solution.
