Abstract

UNAS COMPOSICIONES QUE CONTIENEN AL MENOS DOS UNIDADES DIACIDAS AROMATICAS, LAS CUALES SON SOLUBLES EN CLOROFORMO O DICLOROMETANO PARA CONCENTRACIONES ENTRE APROXIMADAMENTE 0.5 A 50% EN PESO/VOLUMEN, FUNDIDAS A TEMPERATAURAS BAJO 180 C Y QUE TIENEN UNA CRISTALIZACION BAJA. LOS COPOLIMEROS PUEDEN CONTENER ENTRE 0 Y APROXIMADAMENTE 30% DE UNIDADES DIACIDAS ALIFATICAS. TODOS LOS COPOLIMEROS SON INSOLUBLES EN TETRACLORURO DE CARBONO, EJ: MENOS DE UN 0.1% DE POLIMERO POR PESO/VOLUMEN DE DISOLVENTE. LAS PROPIEDADES DESEADAS SON EL RESULTADO DE AÑADIR ENTRE 10 Y 90% DE UN SEGUNDO DIACIDO AROMATICO, A LA COMPOSICION COPOLIMERA QUE INTRODUCE LA IRREGULARIDAD EN LA CADENA DE POLIMERO QUE ALTERA DRASTICAMENTE SUS PROPIEDADES, DECRECIENDO LA CRISTALINIDAD Y EL PUNTO DE FUSION E INCREMENTANDO LA SOLUBILIDAD EN LOS DISOLVENTES COMUNES, DICLOROMETANO O CLOROFORMO. SE OBTIENEN UN DECRECIMIENTO ADICIONAL EN TG Y MP, CON AUMENTO DE FLEXIBILIDAD, AÑADIENDO UNA PEQUEÑA CANTIDAD DE DIACIDO ALIFATICO, SOBRE UN 30%.
