Abstract

LA INVENCION DESCRIBE UN NUEVO PROCEDIMIENTO DE RECICLAJE DE POLIESTERES. DE ACUERDO CON EL PROCEDIMIENTO DESCRITO, UN POLIESTER USADO O FRAGMENTOS DE POLIESTER SE HACE REACCIONAR CON GLICOL PARA PRODUCIR UN MONOMERO U OLIGOMERO DE BAJO PESO MOLECULAR, POR DESPOLIMERIZACION DE DICHO POLIESTER. DICHO MONOMERO U OLIGOMERO, SEGUN SEA EL CASO, SE PURIFICA A CONTINUACION UTILIZANDO UNA O MAS DE LAS SIGUIENTES FASES: FILTRACION, CRISTALIZACION Y, OPCIONALMENTE, TRATAMIENTO CON ADSORBENTE O EVAPORACION. EL MONOMERO U OLIGOMERO ASI PRODUCIDO ES ESPECIALMENTE ADECUADO COMO MATERIAL BRUTO PARA LA PRODUCCION DE POLIESTER DE TIPO DE EMBALAJE A BASE DE ACIDOS O ESTERES. DEBIDO A QUE EL PROCEDIMIENTO INCLUYE FASES DE PURIFICACION, LOS REQUISITOS REFERENTES AL MATERIAL DE POLIESTER USADO NO TIENEN QUE SER ESTRICTOS.
