Abstract

Patente de Invenção: <B>"ESTABILIZAçãO DE COR E HIDROLìTICA APRIMORADAS DE RESINAS DE POLICARBONATO"<D>. Uma composição de policarbonato aromática apresentando estabilidade de cor aprimorada e estabilidade hidrolítica aprimorada, embora mantendo propriedades de processamento boas, cuja composição consiste de um policarbonato aromático e um sistema estabilizador consistindo de, no mínimo, um aditivo contendo fósforo orgânico e uma tetra-amina de hexanetileno. O sistema estabilizador é aquela quantidade suficiente para fornecer estabilidade de cor aprimorada quando comparada ao emprego de um estabilizador de fósforo apenas. Preferivelmente a quantidade de estabilizador empregada é de cerca de 0,01 a cerca de 0,30% em peso, baseado no peso total da resina de policarbonato e do estabilizador. Também está incluído neste trabalho um processo de preparação de artigos, tais como artigos moldados por injeção ou extrusados, particularmente lâmina de policarbonato transparente apresentando as propriedades aprimoradas demonstradas acima.
