Abstract

o uso do agente de condensação induzida (ica), em sistemas de reator em fase gasosa de leito fluidizado permite taxas de produção mais elevadas, mas pode afetar o índice de fusão das poliolefinas resultantes. o efeito do aumento da concentração de ica pode ter sobre um índice de fusão pode ser neutralizado, se necessário, alterando a concentração do monômero de olefina dentro do sistema do reator.
