Abstract

Prezenta inventie se refera la un procedeu pentru obtinerea unor rasini alchidice prin reactia dintre uleiuri sau acizi grasi din uleiuri vegetale sau acizi grasi sintetici cu polioli si, eventual, cu glicoli, la 190...200 degree C, dupa care se adauga anhidrida ftalica si maleica, continuîndu-se poliesterificarea la 200...250 degree C, si constituie o perfectionare a inventiei principale, cu descrierea nr.58825. Rezulta rasini cu proprietati peliculogene îmbunatatite.The present invention relates to a process for obtaining alkyd resins by reacting oils or fatty acids from vegetable oils or synthetic fatty acids with polyols and optionally with glycols at 190 DEG to 200 DEG C. and then adding phthalic anhydride and the maleic, continuing the polyesterification at 200 ... 250 ° C, and constitutes a refinement of the main invention, with the disclosure of U.S. Pat. Resulting resins with improved film properties.
