Abstract
"POLìMEROS DE ETILENO DE MéDIA DENSIDADE, PROCESSO PARA PREPARAR ESTES POLìMEROS E USO DE AGENTES DE TRANSFERêNCIA DE CADEIA CONTENDO GRUPO CARBONILA NESTE PROCESSO". A presente invenção relaciona-se a um homo ou copolímero de etileno tendo uma densidade entre 0,923 e 0,935 g/cm³, tendo uma distribuição de peso molecular M~ w~/M~ n~ entre 3 e 10, e compreendendo de 0,10 a 0,50 por cento em peso de unidades derivadas de um composto contendo grupo carbonila, baseado no peso total do homo ou copolímero. Em adição, a invenção relaciona-se a um processo de polimerização de iniciação de radical livre para a preparação de polímeros ou copolímeros de etileno de média densidade, compreendendo reagir etileno e opcionalmente um ou mais comonómeros em uma alta pressão, convenientemente entre 1600 e 4000 kg/cm², e a temperaturas de cerca de 150-330°C em um sistema de reator consistindo de pelo menos um reator de autoclave ou de uma combinação de reatores de autoclave e tubular, na presença de iniciadores de radical livre e um composto contendo grupo carbonila. Finalmente, a invenção relaciona-se a agentes de transferência de cadeia contendo grupo carbonila para obter propriedades de processamento e desempenho de polímero melhoradas em processos e aplicações de extrusão de matriz plana.
