Abstract

"PRé-POLìMERO TERMINADO EM ISOCIANATO, COMPOSIçãO DE POLIISOCIANATO, E, PROCESSO PARA A PREPARAçãO DE UMA ESPUMA DE POLIURETANO FLEXìVEL". Pré-polímero terminado em isocianato que tem um valor de NCO de 5-30% em peso e que é o produto de reação de uma quantidade excessiva de diisocianato de difenilmetano que consiste de pelo menos 80% em peso de diisocianato de 4,4<39>-difenilmetano e um polioxietileno-polioxipropileno poliol que tem um peso molecular médio de 2000-10000, uma funcionalidade de hidróxi nomilial média de 2-6, um teor de oxietileno de 21-45% em peso e uma estrutura do tipo -PO-PO/EO-EO em que o bloco de PO consiste de 60-90% do PO e a razão de EO de extremidade: aleatório é 3:1 a 1:3, e um processo para a preparação de uma espuma flexível através de reação em um molde e em um indice de 70-120, o pré-polímero acima ou uma composição que compreende este pré-polímero e b1) um polioxietileno-polioxipropileno poliol, que tem uma funcionalidade de hidróxi nominal média de 2-6, e um teor de oxietileno (EO) maior do que 50% em peso; e opcionalmente 2) um polioxietileno-polioxipropileno poliol, que tem uma funcionalidade de hidróxi nominal média de 2-6, um teor de EO de entre 2050% em peso e um teor de hidróxi primário de pelo menos 50%, calculados sobre o número de grupos de hidroxila primária e secundária; e c) água; e opcionalmente d) aditivos e auxiliares conhecidos de per si.
