    Description / Table of Contents: Einige neue Thiodicarbonsäuren und neue Thiodiole wurden erhalten durch Kondensation von 4,4′-Bis(mercaptomethyl)benzophenon (BMMB) mit Halogensäuren oder Halogenalkoholen in wäßriger Natriumhydroxidlösung.Bei der Polykondensationsreaktion einer dieser Säuren, und zwar der Benzophenon-4,4′-bis(methylthioessigsäure) mit 1,5-Pentandiol, wurde ein neuer linearer Polyester erhalten (Schmelzreaktion). Durch Polyaddition des Benzophenon-4,4′-bis(methylthiohexanol)s (BBMTH) mit Hexamethylendiisocyanat (HDI) wurde ein neues lineares Polyurethan erhalten.Die Struktur dieser Monomeren und Polymeren wurde durch Elementaranalyse sowie FT-IR und 1H-NMR Spektroskopie bestätigt. Die physikochemischen, thermischen und mechanischen Eigenschaften der erhaltenen Polymeren wurden untersucht.
    Notes: A few new thiodicarboxylic acids and thiodiols were obtained by condensation reaction of 4,4′-bis(mercaptomethyl)benzophenone (BMMB) with some halogen acids or halogen alcohols, respectively, in aqueous sodium hydroxide solution.By melt polycondensation of one of these acids, i.e. benzophenone-4,4′-bis-(methylthioacetic acid) (BBMTAA) with 1,5-pentanediol, a new linear polyester was obtained, and by melt polyaddition of one of these diols, i. e. benzophenone-4,4′-bis(methylthiohexanol) (BBMTH) with hexamethylene diisocyanate (HDI) a new linear polyurethane was obtained.The structures of monomers and polymers were confirmed by elemental analysis and FT-IR and 1H NMR spectroscopy. The polymers were studied to describe their physicochemical, thermal and mechanical properties.

    Notes: New polythioesters by interfacial polycondensation of 4,4′-di(mercaptomethyl) benzophenone with oxalyl, succinyl, adipoyl, suberoyl, and sebacoyl chlorides were obtained. To determine the optimal conditions for interfacial polycondensation the influence of the following factors on yield and value of reduced viscosity were studied: type of organic phase, the quantitative ratio of aqueous and organic phase, concentration of hydrogen chloride acceptor, molar ratio of reagents, temperature of reaction, rate of acid chloride addition, and contribution of catalyst and emulsifier. A thorough examination was carried out only for polycondensation of dithiol with adipoly and sebacoyl chlorides. The structure of all polythioesters obtained under the model conditions was determined by elementary analysis and infrared spectra. Initial decomposition and initial intensive decomposition temperature were defined from the curves of thermogravimetric analysis. Some mechanical and electrical properties of the polythioesters obtained from 4,4′-di(mercaptomethyl)benzophenone and adipoyl and sebacoyl chlorides were determined. The molecular weight was not measured because of the low solubility of the obtained polythioesters.

    Notes: New polythioesters have been obtained in the interfacial polycondensation of 4,4′-di(mercaptomethyl)benzophenone with terephthaloyl, isophthaloyl and phthaloyl chlorides. The reactions were carried out at room temperature with the use of 10% excess of acid chloride per mole of mercaptan with vigorous stirring (2000 rpm). The organic phase was composed of benzene and hexane in equal volumes and the ratio of this mixture to water also was 1:1. The structure of the polythioesters was determined from elementary analysis and the infrared spectra. The molecular weight was not determined because of the very low solubility of polythioesters. Some thermal, mechanical, and electrical properties of the products have been determined. Products of dimercaptan with the terephthaloyl and isophthaloyl chlorides show the best properties.

    Notes: Several new polyesters containing sulfur in the main chain were obtained by melt polycondensation of diphenylmethane-4,4′-di(methylthioacetic acid) with ethanediol, 1,3-propane diol, 1,4-butanediol, 1,5-pentenediol, 1,6-hexanediol, 1,2-propanediol, and 2,2′-oxydiethanol. The structure of all polyesters was determined from elemental analysis and infrared (IR) spectra. Yield, reduced viscosity, molecular weight, and softening temperature for reaction products have been found. Initial decomposition and initial intensive decomposition temperature were defined from the curves of thermogravimetric analysis.

    Notes: New polythioesters of better physicochemical and mechanical properties have been obtained by interfacial polycondensation of 4,4′-di(mercaptomethyl)benzophenone with terephthaloyl, isophthaloyl, and phthaloyl chlorides with the use of sodium hydroxide excess as a hydrogen chloride acceptor. According to preliminary experiments, the best yield and the highest reduced viscosity are reached when the polycondensation at a 1:l ratio of the aqueous to the organic phase is carried out at a temperature of 5-7°C with a little excess of acid chloride with addition time of 0.5-2 min in the presence of 100% excess of NaOH as hydrogen chloride acceptor. The structure of the polythioesters was determined from elemental analysis and infrared spectra. Thermal properties of all polythioesters were determined. Mechanical and electrical properties of only the most interesting polythioesters obtained from isophthaloyl chloride were determined.

    Notes: The new linear polyesters containing sulfur in the main chain were obtained by melt polycondensation of diphenylmethane-4,4′-di(methylthiopropionic acid) with ethanediol, 1,3-propanediol, 1,4-butanediol, 1,5-pentanediol, 1,6-hexanediol, 1,2-propanediol, 1,3-butanediol, and 2,2′-oxydiethanol. Low-molecular weights, low-softening temperatures and, very good solubility in organic solvents are their characteristics. The structure of all polyesters was determined by elemental analysis, FT-IR and 1H-NMR spectroscopy, and x-ray diffraction analysis. The thermal behavior of these polymers was examined by differential thermal analysis (DTA), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The kinetics of polyesters formation by uncatalyzed melt polycondensation was studied in a model system: diphenylmethane-4,4′-di(methylthiopropionic acid) and 1,4-butanediol or 2,2′-oxydiethanol at 150, 160, and 170°C. Reaction rate constants (k3) and activation parameters (ΔG≠, ΔH≠, ΔS≠) from carboxyl group loss were determined using classical kinetic methods. © 1997 John Wiley & Sons, Inc.
