Abstract
Inventia se refera la un procedeu de obtinere a anhidrifelor polialchenilsuccinice conform caruia se utilizeaza un raport molar între reactanti de 0,8.....1,2 mol anhidrida maleica echivalent gram clor, lucrand în prezenta de 0,3.....0,6% în greutate inhibitor de izomerizare, reprezentat de acid acetic sau anhidrida acetica, reactia fiind efectuata timp de 10.....15 h la temperatura de 180....220 degree C, cu eliminarea anhidridei maleice nereactionate prin stripare la 200 degree C, timp de o ora la o presiune remanenta 10....20 mm Hg.
