Abstract

resumo “processo para produzir uma composição de polietileno” a presente divulgação provê um processo para produzir polietileno de baixa densidade com um fator de dissipação menor ou igual a 1,48 x 10-4 radiano em 2,47 ghz. o processo inclui polimerização em alta pressão via radicais livres de etileno e separação das espécies não reagidas do polietileno resultante para formar uma corrente de reciclagem. o processo inclui ainda purgar componentes dissipativos da corrente de reciclagem. a corrente de reciclagem é então introduzida no reator de polimerização. 1
