Abstract

"PROCESSO PARA A PREPARAçãO DE UM POLìMERO DE VINILPIRROLIDONA DE ALTA PUREZA". Pode ser proporcionado um processo para preparação de um polímero de vinilpirrolidona de alta pureza que se dissolva com limpidez em um solvente orgânico. o processo para a preparação de um polímero de vinilpirrolidona de alta pureza, em que a vinilpirrolidona é polimerizada por meio do uso de um iniciador redox, compreendendo um peróxido orgânico e um sulfito e, daí em diante, o produto é posto em contato com uma resina de troca aniónica para ser purificado.
