Abstract

PROCEDIMIENTO PARA LA OBTENCION DE POLIARILENSULFUROS. CONSISTENTE EN HACER REACCIONAR P-DIHALOGENOBENCENOS, UN AROMATO POLIHALOGENO ARXN Y UN SULFURO ALCALINO EN UN DISOLVENTE POLAR, PREFERNATEMENTE EN UNA AMIDA O LACTAMA. LOS P-DIHALOGENOBENCENOS SE COMPONEN DE 50 HASTA 100 POR 100 MOLES DE COMPUESTOS DE FORMULA (I) Y DE 0 HASTA 50 POR 100 MOLES DE COMPUESTOS DE FORMULA (II), EN CUYAS FORMULAS X SIGNIFICAN HIDROGENO, C1-C20-ALQUILO, C5-C20-CILOALQUILO, C6-C24-ARILO, C7-C24-ALCARILO O C7-C24-ARALQUILO, DONDE, SIN EMBARGO, COMO MINIMO, UN R ES DISTINTO DE HIDROGENO. EN EL AROMATO ARXN, AR SIGNIFICA UN RESTO AROMATICO ARTIBRARIO CON 6 HASTA 24 ATOMOS DE CARBONO Y, COMO MINIMO, TRES VALENCIAS LIBRES, SIENDO N > 3, ESTANDO SU PROCENTAJE COMPRENDIDO EN 0 HASTA 2 POR 100 MOLES, REFERIDO A LA PARTE DE P-DIHALOGENOBENCENO. EL TIEMPO DE POLICONDENSACION ES DE HASTA SESENTA HORAS -PREFERENTEMENTE DE DOS HASTA QUINCE HORAS- A UNA TEMPERATURA ENTRE 160 Y 285C, PREFERENTEMENTE ENTRE 190 Y 275C. LOS COMPUESTOS OBTENIDOS SON MATERIALES SINTETICOS TERMOPLASTICOS.
