Abstract
Prezenta inventie se refera la un procedeu de obtinere a unor oligoesterfumarati cu reactivitate marita prin reactia dintre monomeri de policondensare liniari, cu functii hidroxil si/sau carboxil, de preferinta pe baza de anhidrida maleica în proportie de 9...75% din totalul de echivalenti, conferind astfel libertate rotationala lantului esteric în prezenta de catalizatori de izomerizare cis-trans pe baza de sulf azot sau fosfor, si/sau catalizatori de poliesterificare constînd din acizi organici (benzensulfonic, para-toluen sulfonic), saruri de metale din grupa acetati, benzoati, octoati de Cu, Zn, Al, Pb, reactia de acilare avînd loc în etape la temperaturi de maximum 120 degree C pentru anhidrida si maximum 165 degree C pentru diacizi, pîna la o conversie de 55...65% a grupelor acide, prin care, în scopul maririi gredului de conversie al dublelor legaturi din izomerul cis în izomerul trans si al reducerii duratei de poliesterificare, utilizeaza 0,01...1,5 parti în greutate catalizatori de izomerizare cis-trans pe baza de sulf sau azot si/sau 0,01...0,5% catalizatori de izomerizare pe baza de fosfor, cantitatile respective fiind raportate la 1 mol de anhidrida maleica, iar catalizatorii de poliesterificare se introduc în mediul de reactie la temperatura de 200 degree C si la o conversie a grupelor acide de 75...80%.
