Abstract
LA PRESENTE INVENCION SE REFIERE A LA PRODUCCION DE POLIURETANOS CON BASE DE ACIDO LACTICO. EN LA PRIMERA FASE DE LA PRODUCCION, EL ACIDO LACTICO MONOMERICO SE POLIMERIZA EN UN OLIGOMERO QUE TIENE UN PESO MOLECULAR DE UNOS 500 HASTA 10.000. A CONTINUACION, EL OLIGOMERO DE ESTE MODO OBTENIDO SE COPOLIMERIZA CON UN ISOCIANATO QUE REACCIONA CON LOS GRUPOS CARBOXILO E HIDROXILO DEL OLIGOMERO PARA PRODUCIR UN POLIURETANO DE PESO MOLECULAR ALTO. NO ES NECESARIO QUE EL ACIDO LACTICO UTILIZADO SEA TOTALMENTE PURO. SE PUEDEN OBTENER DE FORMA APROPIADA VARIOS PRODUCTOS FINALES BIODEGRADABLES PARA UTILIZARLOS COMO MATERIAL PARA PAQUETES DISTRIBUIDORES, LAMINAS AGRICOLAS, TIESTOS DE SIEMBRA O REVESTIMIENTOS PARA GRANOS DE ABONO.
