Abstract
são divulgados aqui métodos de controlar as propriedades de polímero em processo de polimerização que utilizam um catalisador baseado em cromo. uma modalidade divulga um método de produzir uma poliolefina compreendendo: colocar em contato uma mistura de reação e um catalisador de óxido de cromo reduzido em um reator de fase gasosa para produzir a poliolefina, em que a mistura de reação compreende um monômero e um comonômero; e mudar a temperatura de reação no reator de fase gasosa em cerca de 1°c ou mais pela qual uma proporção molar de gás do comonômero para o monômero é mudada em cerca de 2% ou mais e um conteúdo de comonômero da poliolefina em densidade substancialmente constante é mudado em cerca de 2% ou mais. métodos adicionais e composições também são fornecidos.
