Abstract
Inventia se refera la un procedeu pentru obtinerea unor rasini dure pentru lacuri pe baza de derivati celulozici, conform caruia, în scopul realizarii unor poliesteri cu intervale de topire 40...150 degree C, se supun copoliesterificarii 1...50% în greutate colofoniu, 0,01...2,5% în greutate anhidrida maleica sau acid fumaric, 10...30 în greutate polioli alesi dintre etilenglicol, propilenglicol, neopentilglicol, pentaeritrita si 10...50% în greutate acizi dicarboxilici alesi dintre anhidrida ftalica si acid tereftalic, la temperatura de 150...200 degree C, în prezenta de gaz inert sau/si solvent insolubil în apa, pentru îndepartarea apei de reactie în vederea deplasarii echilibrului de copoliesterificare.
