Abstract

Patente de Invenção: <B>"PROCESSO PARA EVAPORAR SOLUçõES DE POLìMEROS DE POLìMEROS TERMOPLáSTICOS"<D>. A invenção refere-se um processo de várias etapas para evaporar soluções de polímeros de polímeros termoplásticos e para remover componentes voláteis de polímeros termoplásticos por troca de cloreto de metileno indireta. Especialmente a invenção refere-se a um processo para evaporar componentes voláteis de soluções de polímeros com o emprego de trocadores de calor com feixe tubular (4, 7) de geometria especial, evaporadores de tubos em serpentina (17, 21) e evaporadores de extrusão.
