Abstract
PROCEDIMIENTO PARA PREPARAR POLIMEROS Y COPOLIMEROS DE UN HALURO DE VINILO. SE POLIMERIZA EN MASA O EN SUSPENSION EL HALURO DE VINILO, QUE PUEDE SER CLORURO DE VINILO O CLORURO DE VINILIDENO, EN PRESENCIA DE UN SISTEMA DE CATALIZADOR REDOX, QUE CONSISTE EN UN COMPUESTO PEROXIGENADO, SELECCIONADO ENTRE PEROXIESTERES: PUEDE SER DE ALQUILO DE ACIDOS CARBOXILICOS ALIFATICOS, DE ACIDOS CARBOXILICOS AROMATICOS O ACIDO CARBONICO, Y PEROXIDOS DE DIACILO, COMO PEROXIDO DE LAUROILO O PEROXIDO DE BENZOILO. TAMBIEN ESTA PRESENTE UN AGENTE REDUCTOR SELECCIONADO ENTRE MERCAPTIDAS ESTANNOSAS Y DE ANTOMONIO (III). LA TEMPERATURA DE OLIMERIZACION DEBE SER SUFICIENTE PARA QUE EL COMPUESTO PEROXIGENADO TENGA UNA VIDA MEDIA DE MAS DE CINCUENTA HORAS, EN AUSENCIA DEL AGENTE REDUCTOR . ESTA TEMPERATURA DEBE ESTAR COMPRENDIDA ENTRE -50 Y +70C. EN LA POLIMERIZACION PUEDE ESTAR PRESENTE UN AGENTE FORMADOR DE COMPLEJOS, COMO CETONAS, ACIDOS CARBOXILICOS, LACTONAS Y ESTERES CARBOXILICOS.
