Abstract

PROCESSO PARA A PRODUçãO DE UM POLIISOCIANATO, E, POLILSOCIANATO Um processo para a produção de um poliisocianato composto de (a) fosgenação de uma poliamina para formar um poliisocianato através da reação (1) de uma poliamina, a poliamina na qual o poliisocianato é baseado em solução está em um solvente inerte com (2) fosgênio, opcionalmente em solução em um solvente inerte, (b) a separação do solvente do poliisocianato, (c) o tratamento do solvente separado para ser reutilizável na solução de poliamina (1) com um catalisador de trimerização de isocianato.
