Abstract

PROCEDIMIENTO PARA LA PREPARACION DE COPOLIESTERES FORMADORES DE FIBRAS, CONSTITUIDOS ESENCIALMENTE POR UNIDADES DE FORMULAS ESTRUCTURALES (I), (II), (III) Y (IV), DONDE X Y R SON INDEPENDIENTEMENTE HIDROGENO, METILO O CLORO. CONSISTE EN SOMETER A UNA REACCION DE POLIMERIZACION LOS MONOMEROS CORRESPONDIENTES A CADA UNA DE LAS UNIDADES CITADAS EN LAS PROPORCIONES MOLARES APROPIADAS, MEDIANTE CALEFACCION EN AUSENCIA DE OXIGENO Y A UNA TEMPERATURA COMPRENDIDA ENTRE 200 Y 375. LAS PROPORCIONES EN QUE INTERVIENEN CADA UNA DE LAS UNIDADES CITADAS SON: DE 56 A 70 MOLES POR 100 DE LA UNIDAD DE FORMULA (I), DE 10 A 20 MOLES POR 100 DE LA UNIDAD DE FORMULA (II), DE 7 A 12 MOLES POR 100 DE LA UNIDAD DE FORMULA (III), Y UNA CANTIDAD DE LA UNIDAD DE FORMULA (IV) QUE SEA EQUIVALENTE, SOBRE UNA BASE MOLAR, A LA CANTIDAD DE LAS UNIDADES DE FORMULAS (II) Y (III). DE USO EN HILATURA POR FUSION, OBTENIENDOSE FILAMENTOS CON BUENA TENACIDAD Y ELEVADO MODULO.
