Abstract

LOS SISTEMAS CATALITICOS LANTANIDOS Y ACTINIDOS NORMALMENTE PARECEN SER "PSEUDO VIVIENTES" CUANDO SE USAN PARA POLIMERIZAR MONOMEROS DIOLEFINICOS CONJUGADOS. LAS POLIMERIZACIONES CATALIZADAS CON DICHOS CATALIZADORES PRODUCEN POLIMEROS CUYO PESO MOLECULAR AUMENTA AL HACERLO LA CONVERSION DEL MONOMERO. EN CONSECUENCIA CUALQUIER CAMBIO EN EL TIEMPO DE POLIMERIZACION O EN LA CONVERSION PUEDE AFECTAR AL PESO MOLECULAR FINAL DEL POLIMERO. ESTO HA HECHO DIFICIL CONTROLAR EL PESO MOLECULAR DE POLIMEROS QUE SE HACEN UTILIZANDO CATALIZADORES LANTANIDOS Y ACTINIDOS. SE HA DESCUBIERTO INESPERADAMENTE QUE LOS HALUROS VINILICOS PUEDEN USARSE COMO REGULADORES DEL PESO MOLECULAR PARA POLIMERIZACIONES CATALIZADAS CON CATALIZADORES LANTANIDOS Y ACTINIDOS. DE ACUERDO CON ELLO, LA PRESENTE INVENCION SE REFIERE A UN PROCESO QUE COMPRENDE POLIMERIZAR AL MENOS UN MONOMERO DIOLEFINICO CONJUGADO EN PREENCIA DE A) UN CATALIZADOR FORMADO POR: 1) UN COMPUESTO ORGANOALUMINICO, 2) UN COMPUESTO ORGANOMETALICO QUE CONTIENE UN METAL DEL GRUPO III-B DEL SISTEMA PERIODICO Y 3) AL MENOS UN COMPUESTO QUE CONTIENE POR LO MENOS UN ION HALURO LABIL; Y B) UN HALURO VINILICO.
