Abstract
LA INVENCION SE REFIERE A ESPUMAS DE POLIURETANO RIGIODO, HIDROFILICO, DE CELDA ABIERTA, OBTENIDAS MEDIANTE LA REACCION EN LA PRESENCIA DE AGUA COMO AGENTE ESPUMANTE Y UN POLIOL DE POLIETER INICIADO CON POLIAMINA POLIHIDRICA. EL POLIOL DE POLIETER SE INICIA CON UNA POLIAMIDA POLIHIDRICA QUE TENGA ENTRE 3 Y 5 HIDROGENOS DE AMINO ACTIVOS Y TIENE BLOQUES INTERNOS DE GRUPOS DE POLIOXIETILENO. LA ESPUMA RETIENE ENTRE 15 Y 35 VECES SU PESO EN AGUA.
