    Description / Table of Contents: Résumé On a étudié l'influence de la nature du copolymère et de sa teneur en comonomère ainsi que celle de la structure supermoléculaire sur le comportement thermique des copolymères binaires de l'acrylonitrile avec le vinylacétate et l'α-méthylstyrène. On a établi une corrélation entre ces résultats et ceux d'études granulométriques et microscopiques.
    Abstract: Zusammenfassung Der Einfluss der Beschaffenheit und des Comonomergehaltes des Copolymeren, sowie der supermolekularen Struktur auf das thermische Verhalten des binären Vinylacetat-sowie desα-methylstyrolcopolymeren von Acrylnitril wurde untersucht. Die Ergebnisse wurden mit granulometrischen und mikroskopischen Untersuchungen verglichen.
    Notes: Abstract The influence of the copolymer nature, its comonomer content and the supermolecular structure on the thermal behaviour of the binary vinyl acetate andα-methylstyrene copolymers of acrylonitrile have been studied. The results have been correlated to granulometric and microscopic studies.

    Notes: Pyrolysis, in combination with gas-chromatography technique, was used in the determination of the structure and study of the thermal degradation mechanism of the condensation polymers obtained by Friedel-Crafts reactions of poly(vinyl chloride) with benzene, toluene, and naphthalene. The separation of the pyrolysis products was made using a column packed with chromosorb W (80-100 mesh) coated with 15% silicone SE-52. The identification of the pyrolysis products resulted as a consequence of the thermal decomposition of condensation polymers and their semiquantitative estimation led to the final conclusion that the initial normal chlorine substitution in the macromolecular chain of poly(vinyl chloride) is followed by an important intramolecular cyclization reaction yielding 1,3-methyleneindan units.
