Macromoleculesrange of dielectric constants (3.5-35) used here. Since the calculated quantities show the same qualitative trends throughout this range of dielectric constants, we would expect our conclusions to hold when a more sophisticated electrostatic potential is employed.Added in Proof If bolaform electrolytes were studied a t a temperature different from the 0 temperature for polymethylene, an additional perturbation would arise from the excluded-volume effect. Since the interaction of the charged chain ends becomes negligible as n becomes infinite, the expansion arising from the excluded-volume effect would dominate for large bolaform electrolytes.
Acknowledgment.ABSTRACT: Flory's equation-of-state theory is applied to a PVF2/it-PEMA system with a lower critical solution temperature. A comparison is made between the observed irregular asymmetric cloud point curve and the calculated spinodals. The agreement is good for values of the mixing parameters, which are in accordance with melting point depression data.ABSTRACT: A review of the preparation and structure/property relationships of various polyquinolines is preaented. The monomer and polymer syntheses and the kinetics, solution properties, morphology, thermal analyses, and cross-linking reactions of polyquinolines are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
