Abstract
Inventia de fata se refera la copolimeri pe baza de diciclopentadiena si la un procedeu de obtinere a acestora. Copolimerii conform inventiei, sînt constituiti din 5...50%, amestec provenit din deseuri rezultate la piroliza fractiunii nafta continînddiciclopentadiena, ciclopentadiena, metildiciclopentadiena, triciclopentadienta sau metiltriciclopentadiena, si 50...95% în greutate acizi grasi naturali nesaturati sau esterii acestora cu glicerina, alesi dintre uleiuri de in, soia, ricin sau ricindeshidratat. Procedeul de obtinere a copolimerilor consta în copolimerizarea amestecului de diene cu acizi grasi nesaturati sau esterii acestora cu glicerina, la temperatura de 230...240 degree C sub agitare puternica, la presiune normala, dupa care amestecul de reactie se încalzeste la 260...280 degree C si se mentine la aceasta temperatura timp de 6...10 h. Acesti copolimeri se folosesc drept lianti pentru lacuri si vopsele.
