Abstract

MÉTODO DE PURIFICAR UM COMPOSTO N-VJNILA DE CADEIA ABERTA, PROCESSO PARA PREPARAR HOMOPOLÍMEROS E COPOLÍMEROS DE MASSA MOLECULAR ALTA, E, USO DE UM POLÍMERO. É revelado um método de purificar um composto N-vinila de cadeia aberta por um processo de cristalização em um cristalizador no qual a cristalização é realizada a partir de uma massa fundida de uma mistura contendo um composto N-vinila de cadeia aberta a uma pressão de 10^ -3^a 400 bar.
