In this study, some thermodynamic properties of poly(2-[3-(6-tetralino)-3-methyl-1-cyclobutyl]-2-hydroxy ethyl methacrylate) P (TMCBHEMA) and poly[2-(3-mesityl-3-methyl-1-cyclobutyl)-2-oxoethyl methacrylate) P (MCBOEMA) such as the adsorption enthalpy, DH a , molar evaporation enthalpy, DH v , the sorption enthalpy, DH 1 s , sorption free energy, DG 1 s , sorption entropy, DS 1 s , the partial molar free energy, DG 1 1 , the partial molar heat of mixing, DH 1 1 , at infinite dilution were determined for the interactions of PTMCBHEMA and PMCBOEMA with selected alcohols and alkanes by the inverse gas chromatography (IGC) method in the temperature range of 333-463 K. According to the specific retention volumes, V g 0 , the weight fraction activity coefficients of solute probes at infinite dilution, V 1 1 , and Flory-Huggins interaction parameters, x 1 12 between PTMCBHEMA and PMCBOEMA-solvents were determined in 433-463K and 443-463K, respectively. According to V 1 1 and x 1 12 , selected alcohols and alkanes were found to be non-solvent for PTMCBHEMA at 433-463 K, but the same solvents (except for decane) were found to be solvent for PMCBOEMA at 443-463K. The glass transition temperature, T g , of the PTMCBHEMA and PMCBOEMA found to be 380 and 383; 390 K and 388 K, by IGC and DSC techniques, respectively.Keywords: poly (2-[3-(6-tetralino)-3-methyl-1-cyclobutyl]-2-hydroxy ethyl methacrylate) and poly [2-(3-mesityl-3-methyl-1-cyclobutyl)-2-oxoethyl methacrylate); inverse gas chromatography; polymer-solvent interactions

“…The retention times of these trace amount liquids are used in determination of their interactions with the solid in the column. Because of these properties, the method is simple, fast, and economical, and provides valuable thermodynamic information for characterization of polymeric materials (1)(2)(3)(4)(5)(6)(7)(8).…”

“…[1][2][3][4][5][6][7][8][9][10] The determination of HSP of polymers and polymer blends in the bulk phase at temperatures higher than the glass transition temperature, T g , can easily be accomplished by the IGC method. Thermodynamic theory [11] enables us to convert the retention volumes measured by IGC into the weight fraction activity coefficients and Flory-Huggins interaction parameters.…”

The specific retention volumes, V 0 g , for 21 solute probes in a cellulose acetate phthalate (CAP)-polycaprolactonediol (PCLD) blend were determined by inverse gas chromatography (IGC) in the temperature range 323.15-413.15 K. The retention diagrams drawn between lnV 0 g vs. 1 T revealed the presence of the glass transition temperature at about 373 K. Therefore, the Flory-Huggins interaction parameters at infinite dilution, χ ∞ 12 , were calculated using V 0 g values in the temperature range 373.15-413.15 K. The χ ∞ 12 values decreased with increase of temperature for all the solutes. Further, the χ ∞ 12 values decreased with decrease of chain length of n-alkanes whereas in 1-alcohols the trend was reversed. The Hansen solubility parameters (HSP) were determined in the temperature range 373.15-413.15 K following the Flory-Huggins solution model. The dispersive and polar components of the HSP decreased with increase of temperature whereas the hydrogen bonding component slightly increased with increase of temperature.

“…The usefulness of IGC for determining polymer–small molecule interactions is well established 4, 6, 7, 8. Experimentally determined retention parameters are easily recalculated into Flory–Huggins parameters, using the equation5, 6: where 1 denotes the solute and 2 or 3 denotes examined material (polymer or filler, accordingly), M 1 is the molecular weight of the solute, p

_{1}^{0}

is thesaturated vapor pressure of the solute, B 11 is the second virial coefficient of the solute, V i is the molar volume, ρ i is the density, R is thegas constant, V g is the specific retention volume.…”

Any quantitative information on the strength of interactions between inorganic filler and polymer is substantial for the future application of the composite. The magnitude of adhesion of two phases may be deduced from results collected by various experimental techniques. Polyether‐urethane/modified carbonate‐silicate fillers systems containing different amount of filler (5, 10, and 20 wt %) were the materials investigated. We propose to express the magnitude of modified filler/polymer interactions by Flory–Huggins χ 23′ parameter. It may be deduced from the results collected by inverse gas chromatographic (IGC) experiment. We have also tried to explain the influence of the solvent on values of the evaluated parameters and to check the usefulness of some of presented methods to minimize Δχ effect. © 2006 Wiley Periodicals, Inc.
