Oppositely Charged

Formation of single globules via 1 : 1 complexation of oppositely charged linear chains occurs prior to coacervation. Fcorr is proved to be negative which is the difference between the random phase approximation (RPA) correction term and the self-energy of the chains.

Preferential Adsorption

It has been shown that in light scattering experiments with polymers replacement of a solvent by a solvent mixture causes problems due to preferential adsorption of one of the solvents. The present paper extends this theory to be applicable to any angle of observation and any concentration by using the random phase approximation theory proposed by de Gennes. The corresponding formulas provide expressions for molecular weight, gyration radius, and the second virial coefficient, which enables measurements of these quantities provided enough information on molecular and thermodynamic quantities is available.
