dc.description.abstractGas-Liquid chromatography (GLC) was used to investigate the sensitivity of GLC data to structural modification in a series of alkyl- and fluoroalkyl- substituted siloxane polymers. Experimental data at 55°C, 70°C, 85°C and essentially atmospheric pressure for each solute in the siloxane polymer systems at infinite dilution are presented. Infinite-Dilution pseudo activity coefficients (Ω∞) and thermodynamic quantities (e. g., ∆Hm, ∆Gm, ∆Sm) were obtained from data taken at 55°C, 70°C and 85°C. The significance of the results to melting transition in polymers, glass transition in polymers, polymer solubility, and the effect of polymer structural modification with solubility are discussed. It is concluded that gas chromatography is a valuable tool for studying the structure of polymers and their interaction with compounds of lower molecular weight.
