Abstract
"PROCESSO DE DIMERIZAçãO CATALìTICA DE ISOCIANATOS". A presente invenção invenção refere-se a um processo de preparação de poliisocianatos por ciclodimerização de funções isocianatos portadas por isocianatos monómeros de partida, caracterizado pelo fato de compreender as etapas de: a) fornecimento de um meio reacional, compreendendo isocianatos monómeros de partida, eventualmente em presença de um solvente; b) adição a esse meio reacional de um catalisador de (ciclo) dimerização, compreendendo um composto da família dos superácidos; c) aquecimento do meio reacional a uma temperatura compreendida no intervalo de 0 a 300<198>C, vantajosamente de 20 a 200<198>C até a obtenção da taxa de transformação desejada; d) eventualmente inativação ou eliminação do catalisador de reação; e e) eventualmente, eliminação dos monómeros que não reagiram.
