Abstract
LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO MEJORADO DE PREPARACION DE DIESTERES DEL POLITETRAMETILENO ETER Y DEL GLICOL CUYA FORMULA ES R - CO - O(CH 2 - CH 2 - CH 2 - CH 2 - O)N - COR 1 A, EN LA CUAL R Y R 1 A SON IDENTICOS O DIFERENTES Y SON RADICALES ALQUILO O SUS DERIVADOS, MEDIANTE POLIMERIZACION DE TETRAHIDROFURANO EN PRESENCIA DE UN CATALIZADOR DE POLIMERIZACION HETEROGENEA Y EN PRESENCIA DE UN ANHIDRIDO CARBOXILICO. SE UTILIZA UN CATALIZADOR DE SILICATO DE ALUMINIO COMPUESTO DE HALOISITO NATURAL ACTIVADO POR UN TRATAMIENTO ACIDO Y CALCINADO, EN VEZ DE LOS SILICATOS CATALITICOS CONOCIDOS COMO LA BENTONITA, LA ZEOLITA O LA CAOLINITA. EL NUEVO CATALIZADOR TIENE UNA DURACION DE VIDA MUY LARGA Y PRODUCE POLIMEROS QUE TIENEN PROPIEDADES MAS UNIFORMES Y UNA DISTRIBUCION DE PESO MOLECULAR ESTRECHA, INCLUSO CON UN MONOMERO RELATIVAMENTE IMPURO.
