Abstract

MéTODO PARA PRODUçãO DE UM POLICARBONATO AROMáTICO DE ALTA QUALIDADE A presente invenção refere-se a um método para produção de um policarbonato aromático de alta qualidade, o qual compreende sujeitar à polimerização em estado fundido uma mistura de um composto de dihidroxila aromático e um carbonato de diarila na presença de um catalisador, a mistura do composto de dihidroxila aromático e do carbonato de diarila sendo obtida por meio de um estágio de mistura no qual um composto de dihidroxila aromática e um catalisador, cada um estando em um estado sólido e/ou em um estado liquido, são adicionados a um carbonato de diarila em um estado fundido na presença de um gás inerte, desta maneira dissolvendo o composto de dihidroxila aromática e o catalisador no carbonato de diarila fundido.
