Abstract
Procedeul conform inventiei efectueaza condensarea la un raport de echivalenta OH/COOH supraunitar si o constanta alchidica mai mare sau egal 1, pe lantul de oligoester introducînd grupari amidice, prin cuplare cu lactame, alese dintre caprolactama, N-metilcaprolactama, la temperatura de 120...180 degree C, excesul de grupe OH fiind cuplat cu anhidrida ftalica sau anhidrida trimetilica; la o temperatura cu 10...30 degree C peste punctul de topire al acidului folosit utilizînd pentru diluarea rasinii cosolventi cu solubilitate limita în apa reprezentati de alcooli alifatici sau cicloalifatici cu 4...6 atomi de C, sau amestecuri ale acestora cu eteri alesi dintre monobutileter, propilenglicolmonobutileterbutanol, monoetilenglicoletileter.
