Interactions between flexible and rodlike macromolecules

2014 We study the interactions between flexible and rodlike macromolecules in solution. If the solvent is a good solvent for the flexible chain, a mean-field theory can be used and the mutual virial coefficient is proportional to the product of the masses of the two polymers. If the solvent is a 03B8 solvent, the two polymers interact as hard spheres when the space dimension is slightly smaller than 3. Logarithmic corrections to the hard sphere behavior are found in three dimensions. In this case the mutual virial coefficient is calculated with the use of des Cloizeaux direct renormalization method. Tome 49 N°12 DECEMBRE 1988 LE JOURNAL DE PHYSIQUE J. Phys.
