Abstract

Patente de Invenção: <B>"PROCESSO PARA A REDUçãO DE RESìDUOS DO REATOR"<D>. é descrito um processo para a redução de resíduos no reator na polimerização de copolímeros de etileno, de alta pressão, iniciada por radical. O processo é caracterizado pelo fato de que um composto contendo silício de redução da aderência é adicionado ao reator de polimerização, preferivelmente em uma quantidade de 0,001 a 3% em peso, com base na quantidade de polímero produzido. De preferência, o composto contendo silício é trimetoxissilano hexadecílico.
