Presence of Isoalkanes in Waxes and Their Influence on Their Physical Properties

摘要: The purpose of this paper is to display the influence isoalkanes on structure and mechanical properties waxes. This work was carried out by means X-ray diffraction, differential thermal analyses, dynamic analyses. Isoalkanes coming from an industrial wax were added in different quantities a synthetic mixture linear alkanes. disorder generated addition estimated diffraction; it modifies structural transformations versus temperature therefore properties. branched chains hinder molecules motions, especially rotation along long axis. Thus, some phases usually formed at high are not observed when increasing temperature. With regard properties, effect alkanes studied using two waxes with Gaussian distribution composition. analyses have shown that storage modulus (E′) also affected isoalkane quantity.
