Abstract

Patente de Invenção: <B>''PROCESSO DE SEPARAçãO DE UM COMPOSTO OBTIDO POR POLIMERIZAçãO DE ISOCIANATOS DOS MONÈMEROS NãO TRANSFORMADOS''<D>. Essa invenção refere-se a um processo de separação de um(uns) composto(s) oligómero(s) ou polímero(s) (A) obtido(s) por polimerização de isocianatos monómeros (A~ 1~) ou copolimerização de isocianatos monómeros com um outro composto polimerizável (A~ 2~), notadamente um poliol, esse(s) composto(s) A apresentando uma viscosidade (a) do(s) monómero(s) não transformado(s), compreendendo a adição a esse(s) composto(s) (A) de um (uns) composto(s) (B) consistindo no produto de polimerização de isocianatos monómeros (B~ 1~) ou de copolimerização de isocianatos monómeros com um outro composto polimerizável (B~ 2~), notadamente um poliol, esse(s) composto(s) (B) apresentando uma viscosidade (b) e a relação das viscosidades b/a sendo inferior a 1/1,5 de preferência inferior a ¢ e a co-destilação de (A) e (B), a fim de separar o(s) composto(s) (A) dos monómeros correspondentes não transformados.
