Abstract

Patente de Invenção: "PROCESSO PARA A PREPARAçãO DE HOMO- E COPOLìMEROS DE ETILENO MEDIANTE INTENSA MISTURA DE UM COMPONENTE DE REAçãO REATIVO COM UM MEIO DE ESCOAMENTO CORRENTE". A invenção refere-se a um processo para a preparação de homo- e copolímeros de etileno em um reator de tubo em pressões acima de 1000 bar e temperaturas na faixa de 120 até 350<198>C mediante polimerização radical, no qual se aduz a um meio de escoamento corrente contendo etileno, regulador de massa molar e eventualmente polietileno, inicialmente pequenas quantidades de iniciadores de cadeias de radicais, depois do que, então se realiza a polimerização. De acordo com a invenção, o meio de escoamento corrente é decomposto inicialmente em dois elementos de volume correntes separados uns dos outros, depois os elementos de volume correntes separados uns dos outros são deslocados por elementos de corrente adequados em rotação em sentido contrário, depois os elementos de volume correntes separados uns dos outros são novamente unidos em um meio de escoamento corrente e depois no momento ou pouco depois da união dos elementos de volume correntes que giram em sentido contrário dos iniciadores de cadeias de radicais são aduzidos na faixa limite retalhada entre os elementos de volume correntes, que giram em sentido contrário. A invenção refere-se também a um dispositivo para a execução deste processo.
