Abstract

''MéTODO PARA CONTROLAR O PESO MOLECULAR E A DISTRIBUIçãO DO PESO MOLECULAR EM POLìMEROS PRODUZIDOS USANDO UM CATALISADOR DE SìTIO úNICO'' Em um processo de polimerização utilizando um catalisador de sítio único, é proporcionado um aperfeiçoamento que compreende o controle do peso molecular, distribuição do peso molecular, ou ambos por meio da introdução de um modificador de propriedade física selecionado a partir do grupo consistindo de um hidrocarboneto alifático, incluindo um hidrocarboneto alicíclico, um hidrocarboneto aromático, e misturas deles provenientes.
