Abstract

"PROCESSOS PARA A PREPARAçãO DE ESPUMAS DE POLIURETANO E DE SISTEMAS DE INIBIDORES, INIBIDORES PARA POLIURETANOS, USO DOS MESMOS, E, POLIURETANOS". A invenção refere-se a um processo para a preparação de espumas de poliuretano apresentando estabilidade a longo prazo aperfeiçoada por meio de reação de a) poliisocianatos com b) compostos apresentando pelo menos dois átomos de hidrogênio reativos com grupos isocianato, na presença de inibidores, caracterizado pelo fato de que os inibidores são encapsulados em uma substância que é inerte nas condições da preparação do poliuretano, em particular cera.
