Abstract

LA INVENCION SUMINISTRA UN PROCESO PARA LA PREPARACION DE UN PRODUCTO POLIMERICO CELULAR QUE COMPRENDE LA REACCION DE UN COMPUESTO DE POLIISOCIANATO CON UN COMPUESTO DE ISOCIANATO REACTIVO QUE TENGA UNA FUNCIONALIDAD DE AL MENOS 2, EN LA PRESENCIA DE UN AGENTE INSUFLADOR Y EN LA PRESENCIA DE UN LIQUIDO ORGANICO INERTE QUE SEA SUBSTANCIALMENTE INSOLUBLE EN LA MEZCLA DE REACCION Y QUE ESTE PRESENTE EN LA FASE DISPERSA DE LA EMULSION O LA MICROEMULSION, EL PROCESO SE CARACTERIZA POR QUE EL COMPUESTO DE POLIISOCIANATO CONSISTE EN POLIISOCIANATO DE POLIFENILENO-POLIMETILENO CON UNA FUNCIONALIDAD DE AL MENOS 2.5 Y UN PREPOLIMERO FINALIZADO EN ISOCIANATO Y MODIFICADO CON URETANO, EN EL QUE LA FUNCIONALIDAD DEL ISOCIANATO DEL COMPUESTO DE POLIISOCIANATO ES AL MENOS 2.3 Y EN EL QUE LA CONCENTRACION DE ENLACES DE URETANO EN EL COMPUESTO DEL POLIISOCIANATO SE ENCUENTRA EN LA BANDA DE 1 MILIMOL A 150 MILIMOLES POR CIEN GRAMOS DE COMPUESTO. LA INVENCION TAMBIEN SUMINISTRA UN NUEVO COMPUESTO DE POLIISOCIANATO PARA SU USO EN EL PROCESO Y PRODUCTOS POLIMERICOS CELULARES PREPARADOS DE ACUERDO CON EL PROCESO.
