(717b) Interpolymer Complexes: Effect of Solvent Quality On Structure

The solution behavior and interactions in mixtures of associating polymers can be profoundly affected by the presence in water of polar organic solvents (cosolvents) which are ubiquitous in pharmaceutical, coating and home/personal care formulations.  We present data obtained from small-angle neutron scattering (SANS) measurements and discuss the cosolvent effects in terms of changes in the polymer conformation which in turn affects the polymer complexation.
