Abstract

"PROCESSO PARA A PREPARAçãO DE ESPUMAS DEPOLIURETANO FLEXìVEIS". Processo para a preparação deespumas de poliuretano flexíveis, que compreende os estágios de(a) juntar um componente poliol, um componente de poliisocianato,um agente de sopro, que compreende dióxido de carbono líquido,um catalisador adequado e, opcionalmente, substâncias químicasauxiliares, em uma pressão suficiente para manter o dióxido decarbono em um estado líquido, e (b) liberar a pressão e permitircom que a mistura obtida no estágio (a) reaja como uma espumade poliuretano flexível, em que o componente poliol compreendeum polímero poliol, que consiste de, pelo menos, um poliéter polioltendo uma funcionalidade nominal média de, pelo menos, 2,5,tendo dispersadas no mesmo de 2 a 50%, em peso, com base nopeso total de polímero poliol, de partículas de polímero, em que otamanho de partícula, essencialmente de nenhuma destaspartículas de polímero, excede a 50 mícrons.
