Abstract

POLìMEROS DE POLI (áCIDOS LáCTICOS) RAMIFICADOS E PROCESSO PARA PRODUçãO DOS MESMOS Polímeros de polilactídeos são reagidos com um polímero de acrilato de funcionalidade epóxi, para introduzir ramificação de cadeia longa no polímero. O polímero de acrilato proporciona um meio flexível para introduzir um grau de ramificação controlável no polímero de polilactídeo, com pouco risco de formar estruturas gelificadas ou altamente reticuladas. Os polímeros de polilactídeos ramificados têm excelente propriedades reológicas em fusão, que os tornam mais facilmente processáveis em várias aplicações de processamento em fusão.
