Abstract

"POLìMERO DE POLIURETANO HIDROFìLICO, COMPOSIçãO DE PRé-POLìMERO TERMINADO EM ISOCIANATO E PROCESSO PARA PRODUZIR UMA ESPUMA/GEL DE POLIURETANO". A presente invenção relaciona-se com um pré-polímero terminado em isocianato baseado em MDI adequado para preparar um polímero de poliuretano hidrofílico. A composição baseada em MDI compreende um pré-polímero obtido reagindo uma mistura de isocianato compreendendo isocianato de 2,4<39>-metileno difenila (MDI) e isocianato de 4,4<39>-metileno difenila em uma razão molar de 25:75 a 80:20 com um poliéter poliol tendo um teor de oxietileno de pelo menos 30 por cento em peso.
