Abstract
Procedimiento para la obtención de mezclas de poliisocianatos con un contenido en grupos isocianato, en caso dado parcialmente presentes en forma dimerizada, de un 4-48% en peso, grupos de fórmula SO2-O-, que en caso dado forman parte de un grupo de éster alquílico de ácido arilsulfónico, de un 0,3 hasta 38% en peso, grupos uretano -NH-CO-O de un 0 hasta 25% en peso y grupos alofanato -NH-CO-N-CO-O- de un 0 hasta 28% en peso, ascendiendo los dos últimos grupos mencionados juntos a como mínimo un 0,4% en peso y como máximo a un 28% en peso, y los grupos mencionados en segundo y tercer lugar juntos como máximo a un 38% en peso, caracterizado porque ácidos isocianatoarilsulfónicos que llevan como mínimo dos grupos isocianato, cuyos grupos isocianato se pueden presentar como mínimo parcialmente en forma dimerizada, se hacen reaccionar, en caso dado en mezcla con mono- y/o-poliisocianatos libres de grupos ácido sulfónico, a 0-190ºC, con oxiranos y/o oxenatos, seleccionándose la clasey las proporciones cuantitativas de los reactantes de manera que la cantidad total de los grupos isocianato, inclusive los grupos isocianato, en caso dado presentes en forma dimerizada, con respecto a los grupos ácido sulfónico, sea superior a 1 y al proporción de equivalencia entre los grupos oxirano o bien oxetano y los grupos ácido sulfónico se encuentre entre 0,1 y 10.
