Abstract

"COMPOSIçãO E PROCESSO PARA MELHORIA DE COR DE POLìMEROS CONTENDO NITROXILA". A Invenção refere-se a uma composição que compreende, a) pelo menos um oligómero, um cooligómero, um polímero ou um copolímero ou mesclas dos mesmos, contendo um radical nitroxila livre estável e b) um agente redutor; com a condição de que a composição seja essencialmente isenta de um monómero polimerizável. Um outro assunto é um processo para melhorar a cor de um oligómero, um cooligómero, um polímero ou um copolímero ou mesclas dos mesmos, contendo um radical nitroxila livre estável por adição de um agente redutor ao dito polímero e aquecimento da dita mistura até acima da temperatura do vidro no caso de polímeros amorfos ou acima do ponto de fusão no caso de polímeros cristalinos ou semicristalinos.
