Abstract

polimerização em massa de dienos conjugados usando um sistema catalisador à base de níquel um processo para a preparação de um polidieno, o processo compreendendo as etapas de (i) fornecimento de um monômero de dieno conjugado; (ii) abastecimento de um sistema catalisador à base de níquel ao monômero de dieno conjugado; e (iii) abastecimento de uma base de lewis moduladora ao monômero de dieno conjugado para, assim, polimerizar o monômero de dieno conjugado na presença da base de lewis moduladora, onde a referida etapa de abastecimento de uma base de lewis moduladora é separada da etapa de abastecimento de um catalisador à base de níquel e, onde as referidas etapas de fornecimento do monômero de dieno conjugado, abastecimento do sistema catalisador à base níquel e abastecimento de uma base de lewis formam a mistura de polimerização que inclui menos de 20% por peso do solvente orgânico, com base no peso total da mistura de polimerização.
