Abstract

SE DESCUBREN NUEVAS COMPOSICIONES DE POLIESTER DE MOLDEO, LAS CUALES EXHIBEN INESPERADAS PROPIEDADES DE ABSORCION DE AGUA. LAS COMPOSICIONES DE LA INVENCION INCLUYEN UNA RESINA BASADA EN POLIESTER (LA CUAL PREFERIBLEMENTE ES UN POLI(ALQUILENO) DE TEREFTALATO LINEAL, P.EJ., POLI(BUTILENO) DE TEREFTALATO, O UN CO-POLIESTER ELASTOMERO QUE TIENE UNIDADES ESTERES DE CADENA LARGA DERIVADAS DE LOS CORRESPONDIENTES GLICOLES DE CADENA LARGA DE PESO MOLECULAR 600-6000 Y UNA PROPORCION DE CARBONO A OXIGENO MAYOR DE 2,5 , Y UN CO-POLIESTER ELASTOMERO QUE TIENE UNA MULTIPLICIDAD DE UNIDADES ESTERES DE CADENA LARGA Y CORTA, EN DONDE LAS UNIDADES ESTERES DE CADENA LARGA SON DERIVADAS DE LOS CORRESPONDIENTES GLICOLES DE PESO MOLECULAR 400-3500 Y UNA TASA DE CARBONO A OXIGENO DE ENTRE 2 Y 2,4. PUESTO QUE LAS COMPOSICIONES DE MOLDEO DE POLIESTER DE LA INVENCION EXHIBEN ABSORCION DE AGUA REDUCIDA, SE PUEDEN EMPLEAR SATISFACTORIAMENTE PARA FORMAR PARTES EN LAS QUE ES UN ATRIBUTO FISICO DESEABLE UNA REDUCIDA DILATACION (P. EJ. COMO PARTES MOVILES DE UN COMPONENTE QUE TIENE TOLERANCIAS ESPACIALES CRITICAS).
