Abstract
Inventia se refera la un procedeu pentru obtinerea unor polimeri alchidici modificati cu acizi grasi vegetali conform caruia se efectueaza în prima etapa reactia acizilor grasi vegetali alesi dintre acizi grasi izomerizati si pilioli alesi dintre propilenglicol si glicerina, la temperatura de 140....260 degree C, în cataliza acida, cu obtinerea unor monoesteri dupa care se efectueaza semiesterificarea poliolilor volatili cu anhidride acide la temperaturi mai scazute decat cele necesare esterificarii acizilor grasi si anume la temperaturi de 120....200 degree C de preferinta între 135....160 degree C.
