Abstract

resumo “processo de polimerização para preparar copolímero de polipropileno e propileno (c2 a c8)” a presente invenção refere-se a uma melhoria em processo de polimerização de olefina em fase gasosa tendo densidade aparente de leito de polímero relativamente alta. a melhoria envolve o uso de doadores de elétrons externos mistos ao polimerizar propileno em um reator em fase gasosa tendo um leito de polímero com densidade aparente maior que 129 kg/m3, opcionalmente com um ou mais comonômeros, sendo que o sistema doador de elétrons externo compreende pelo menos um primeiro doador de elétrons externo e um segundo doador de elétrons externo, e sendo que o primeiro doador de elétrons externo é um composto de carboxilato. 1
