Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA PREPARAR DISPERSIONES ESTABLES DE POLIHIDRAZODICARBONAMIDAS QUE CONTENGAN HIDROXILO EN UN COMPUESTO QUE CONTIENE HIDROXILO. LAS DISPERSIONES SE PREPARAN MEDIANTE LA REACCION DE ISOCIANATOS ORGANICOS, COMPUESTOS REACTIVOS DE ISOCIANATO CON UN PESO MOLECULAR QUE OSCILA ENTRE 400 Y 10.000, COMPUESTOS Y REACTIVOS DE ISOCIANATO DE PESO MOLECULAR RELATIVAMENTE BAJO, E HIDRAZINAS O HIDRAZIDAS. MAS ADELANTE LA INVENCION SE REFIERE A LAS DISPERSIONES PREPARADAS MEDIANTE DICHO PROCESO, EL USO DE LAS DISPERSIONES PARA PREPARAR ESPUMAS DE POLIURETANO CON DUREZA EXCEPCIONAL, Y LAS ESPUMAS PREPARADAS DE ESE MODO.
