Heat Capacity and Other Thermodynamic Properties of Linear Macromolecules. IX. Final Group of Aromatic and Inorganic Polymers

Abstract

In this final review, a series of polymers which include aromatic rings and/or inorganic chain atoms are treated. Heat capacities of poly(4,4′-isopropylidenediphenylene carbonate), polyphenylenediamides, polyheteroarylenes, poly(dimethyl siloxane), poly(diethyl siloxane), poly(trimethylsilyl ethylene), poly(dimethylphenylsilyl ethylene), poly(dimethylbenzylsilyl ethylene), poly(vinylene diphenylsilylene), poly(vinylene diphenylgermylene), poly(diethnyl diphenysilylene), poly(diethnyl diphenylgermylene), poly(2,3,4,5-tetraphenyl-1, 1-diethylgermocyclopentadiene), poly(phenylsilsesquioxane), poly[ethylene -N-(β-trimethylsilylethyl)imine] and polysulfones have been reviewed on the basis of measurements on 36 samples reported in the literature. All heat capacity data are compiled and a set of recommended data are derived. Enthalpy and entropy functions are calculated for poly(4,4′-isopropylidenediphenylene carbonate) and poly(dimethyl siloxane).
