Influência do envelhecimento de catalisadores Ziegler-Natta à base de neodímio sobre a polimerização de 1,3-butadieno Influence of ageing of neodymium based Ziegler-Natta catalyst on butadiene polymerization

Influência do envelhecimento de catalisadores Ziegler-Natta à base de neodímio sobre a polimerização de 1,3-butadieno Influence of ageing of neodymium based Ziegler-Natta catalyst on butadiene polymerization

Catalisadores envelhecidos em diferentes tempos (0, 5, 15, 40, 80 e 160 dias) e diferentes temperaturas (10, 25 e 40 °C) foram testados na polimerização 1,4-cis do 1,3-butadieno. Avaliou-se a atividade catalítica bem como as características do polímero obtido (massa molecular e microestrutura). Os r...
