Abstract
Se describe un método para producir poliisobuteno reactivo exento de halogenos que tiene más del 50% molar de dobles enlaces terminales y un peso molecular promedio Mn de 500 a 5000 Daltons mediante la polimerizacion cationica de isobuteno o bien de mezclas de hidrocarburos que contienen isobuteno en la fase líquida, la polimerizacion se lleva a acabo a una temperatura comprendida entre -30 degree C y +40 degree C en un catalizador de polimerizacion heterogéneo que incluye al menos un elemento que actua como promotor seleccionado dentro del primer, segundo, tercer, cuarto, quinto, séptimo y octavo subgrupo de la tabla periodica de los elementos o bien a partir del segundo, tercer, cuarto, quinto o sexto grupo principal de la tabla periodica de la tabla periodica o bien varios elementos de este tipo, cada uno en forma de un compuesto que contiene oxígeno, más zirconio en forma de un compuesto que contiene oxígeno, el catalizador no contiene cantidades técnicamente significativa de halogenos.
