Abstract

Inventia se refera la un procedeu pentru prepararea poliizocinatilor poliizocianurati prin ciclotrimetrizarea catalitica a poliizocianatilor, conform caruia, atunci cînd concentratia dorita în grupe izocianurat este atinsa, reactia se întrerupe prin distrugerea catalizatorului, introducînd fie un compus organic ales dintre monoalcooli primari cu 1...8 atomi de carbon, polioli, fenoli, polifenoli, enoli, cetoxime, silanoli, siloxani sau polsiloxani, fie un uretan rezultat prin reactia dintre un izocianat cu un monoalcool primar sau secundar cu 1...8 atomi de carbon, în asemenea proportie încît raportul molar dintre agentul dezactivator si catalizator sa fie cuprins între 0,5 si 2 de preferinta între 0,8 si 1,5.
