Abstract

PROCEDIMIENTO PARA LA OBTENCION DE ESPUMAS DE POLIURETANO. CONSISTE EN LA REACCION DE UN POLIOL QUE CONTIENE GRUPOS HIDROXILO PRIMARIOS Y UN ISOCIANATO QUE CONTIENE UNA PROPORCION SUSTANCIAL DE ISOMEROS DE TOLUEN-ISOCIANATO. LA REACCION SE LLEVA A CABO EN PRESENCIA DE AGUA, DE UN AGENTE TENSOACTIVO DE SILICONA Y DE UN CATALIZADOR QUE CONSISTE EN UN DERIVADO DEL CARBOXILIATO DE AMONIO CUATERNARIO DE UNA AMINA TERCIARIA QUE NO CONTIENE GRUPOS HIDROXILO REACTIVO. ESTAS ESPUMAS TIENEN APLICACIONES PARA LA FABRICACION DE MATERIALES DE TAPICERIA.
