Abstract

"PROCESSO PARA A CRISTALIZAçãO DE UM PRé-POLìMERO DE NAFTALATO DE POLIETILENO AMORFO CONTENDO COMPONENTES VOLáTEIS E PARA PREPARAR UM POLIéSTER DE ALTO PESO MOLECULAR". é exposto um processo para a cristalização de um pré-polímero de PEN contendo componentes voláteis. A temperatura é mantida em uma temperatura na faixa de cerca de 20‹C acima da Tg e cerca de 10‹C abaixo da Tm enquanto o pré-polímero de PEN é agitado. O pré-polímero de PEN está presente sob a forma de pelotas ou aparas. A pressão durante a cristalização é mantida em um nível mais alto do que a pressão de vapor dos componentes voláteis nas pelotas ou aparas do pré-polímero de PEN, adequadamente na presença de um gás e/ou de um líquido ou uma mistura de líquidos.
