Abstract
Invenţia se referă la un aditiv macromolecular cu efect de scădere a punctului de congelare a ţiţeiurilor cu conţinut moderat de parafine şi la un procedeu de obţinere a aditivului, constituit dintr-o soluţie de 50% în greutate copolimer rezultat prin copolimerizarea a 60...70% mol acetat de vinil cu 40...30% mol diester fumaric mixt, restul de 50% în greutate fiind toluen sau amestec toluen-motorină în proporţie de 1:1. Procedeul constă în copolimerizarea cu acetat de vinil a unui diester fumaric mixt, în prezenţă de peroxid de benzoil, la temperatura de 85...105°C, timp de 12 h, produsul final fiind o soluţie în toluen sau în amestec toluen-motorină, având un conţinut de 50% în greutate substanţă activă.
