Abstract

PROCESSO PARA PREPARAR MISTURAS, E, MISTURA DE POLIISOCIANATO. Processo para preparar misturas compreendendo diisocianatosde difenilmetano e poliisocianatos de polifenilpolimetileno tendo um número de cor HunterLab superior (L) por reação estagiada das misturas correspondentes de difenilmetanodiaminas e polifenilpolimetilenopoliaminas com fosgénio, na presença de pelo menos um solvente, por meio do que em um primeiro estágio os correspondentes cloretos de carbamoila e cloridretos de amina são formados e, por meio do que, em um estágio subseqúente os cloretos de carbamoila residuais são dissociados nos correspondentes poliisocianatos e cloreto de hidrogênio, e os cloridretos de amina são fosgenados para formar finalmente os poliisocianatos correspondentes, em que alguns cloridretos de amina permanecem não reagidos ao ponto em que o excesso residual de fosgênio é removido da mistura de reação.
