Abstract

Patente de Invenção: <B>"MéTODO DE PREPARAçãO DE ESPUMA DE POLIURETANO RìGIDA E COMPOSIçãO PARA ESPUMA DE POLIURETANO RìGIDA"<D>. Um método de preparação de uma espuma de poliuretano rígida que apresenta condutividade térmica aperfeiçoada e uma composição para tal espuma de poliuretano rígida são fornecidos. Na preparação de uma espuma de poliuretano rígida a partir de uma composição que compreende um poliisocianato aromático, um poliol, um agente de sopro, um catalisador, um tensoativo e outros auxiliares, o agente de sopro é uma mistura de ciclopentano e água e o poliol contém um poliol de poliéter preparado através da polimerização de adição de um óxido de alquileno a uma o-toluenodiamina como uma iniciadora.
