Abstract
Inventia se refera la un procedeu de valorificare a deseurilor de poliuretan în care se supun reactiei de aminoliza cu dietanolamina deseuri de spume flexibile, elastomeri termoplastici, elastomeri microcelulari, fibre si filme microporoase, pe bazade poliesteri si diizocianati, sub forma de bucati cu dimensiuni cuprinse între 1 si 300 mm, folosind molare dietanolamina/uretan + carboxil de 0,9...3, la temperaturi între 140 si 190 degree C, sub agitare, iar produsul final, într-un amestec de N,N,N', N'-tetra(2-hidroxietil)-diamide ale acizilor dicarboxilici si compusi diureici tetrahidroxietilati se prelucreaza, prin îndepartarea glicolilor si dietanolaminei nereactionate, prin distilare sub vid.
