Abstract

"PROCESSO DE POLIMERIZAçãO EM FASE GASOSA CONTìNUO, E, USO DE UM VENENO DE CATALISADOR". Em um processo de polimerização em fase gasosa contínuo para preparar homopolímeros e copolímeros de etileno e propeno, no qual etileno, propeno ou uma mistura de etileno ou propeno e <244>-monoolefinas C~ 3~-C~ 8~ é polimerizada na zona de polimerização de um reator de polimerização em fase gasosa em de 30 a 125°C e em uma pressão de 1 a 100 bar na fase gasosa em um leito de polímero finamente dividido na presença de um catalisador, <MU>caracterizado<MV> pelo fato de que o gás do reator é circulado para remover o calor da polimerização, depósitos de polímero na linha de gás circulante são evitados pela dosagem de um veneno de catalisador tendo um ponto de ebulição acima da temperatura máxima dentro da linha de gás circulante ao interior desta linha de gás circulante em, no máximo, uma quantidade tal que ele não prejudique significativamente a produtividade do catalisador no reator.
