Abstract
resumo processo para preparar um material à base de etileno de baixo peso molecular a presente invenção geralmente se refere a um processo para preparar polietilenos, poli-?-olefinas ou poli(co-etileno-?-olefina) tendo pesos moleculares médios ponderais de cadeia principal inferiores a 2500 daltons. o processo utiliza um complexo metal-ligante como pré-catalisador e pode ser conduzido a temperaturas variando de 30ºc a 300ºc. o peso molecular relativamente baixo dos produtos permite controle melhorado de viscosidade para uma ampla variedade de aplicações. 1/1
