Polymer Structures and Properties. Part 4.
Abstract
Theoretical and experimental investigations have been made concerning properties of synthetic polymers in dilute solutions. The dependence of the molecular dimensions of linear polystyrene upon the nature of the solvent and temperature has been studied under 'theta' conditions--when the configuration is 'unperturbed' by interactions of indirectly connected elements of the chain. A rather comprehensive study has been made of the configurational, hydrodynamic, and thermodynamic behavior (as reflected by the second virial coefficient) of linear polystyrene in decalin over a sufficiently wide temperature range that the solvent character ranges from poor to moderately good. The data are used in assessing the validity of current theories. The molecular dimensions of branched polymers in dilute solution and the second virial coefficient are the subjects of theoretical treatments: some pertinent experimental data are also presented. p4
