Abstract

a produtividade do catalisador de um catalisador de poliolefina nos métodos aqui divulgados pode ser aumentada pelo aumento da concentração de um agente de condensação induzido (ica) no sistema de reator. o efeito que a concentração aumentada de ica pode ter sobre um índice de fusão pode ser neutralizado, se necessário, de várias maneiras.
