Abstract

Patente de Invenção:<B>"POLIóIS úTEIS PARA A PREPARAçãO DE ESPUMAS DE POLIURETANO COM RETENçãO APERFEIçOADA DE PROPRIEDADES ISOLANTES, ESPUMAS DE POLIURETANO PREPRADAS COM TAIS POLIóIS E PROCESSOS PARA A PREPARAçãO DESSES POLIóIS"<D>. A presente invenção refere-se a espumas de poliuretano com aperfeiçoada retenção de propriedades isolantes, as quais podem ser preparadas usando-se um ou mais dentre dois novos polióis. Um dos polióis é um poli-éter com fórmula geral (I), onde T é qualquer grupo substancialmente não-reativo com epicloroidrina, exceto com um halogênio, Z é um número inteiro de 0 a 8 tem a fórmula geral (II), onde A é N, S ou O; L é uma ligação covalente ou um grupo de conexão de 1 a 10 carbonos; I é um número inteiro de 1 a 10; J é um número inteiro de 2 a 8; e F é H, L-(((CH~ 2~CH~ 2~O)~ I~ )H)~ J~, um grupo alquila ou aromático se A for N, ou um par de elétrons se A for S ou O, preparado mediante reação de um monoepóxido com um composto com fórmula geral (III), onde X é H, Li, Na, K; A é N, S ou O; L é uma ligação covalente ou um grupo de conexão de 1 a 10 carbonos; M é qualquer grupo capaz de reagir com uma molécula de óxido de etileno na presença de um catalisador básico; e J é um número inteiro de 2 a 8. O outro poliol é é preparado através de (1) mistura de carbonato de etileno e um ou mais compostos com função hidroxila sob condições de reação suficientes para reagir o carbonato de etileno e os compostos com função hidroxila, para produzir um precursor de poliol, e de (2) mistura do precursor de poliol com dietileno glicol e um anidrido, um ácido dicarboxílico, um ácido tricarboxílico ou misturas dos mesmos, opcionalmente na presença de um catalisador.
