Abstract
Patente de Invenção: <B>"MéTODO PARA A REDISTRIBUIçãO DE POLICARBONATO COM A DECOMPOSIçãO DO CATALISADOR"<D>. A redistribuição de composições de policarbonato é efetuada na presença de um hidróxido de tetra organo fosfónio como catalisador e uma quantidade de decomposição de catalisador de um composto poli hidróxialifático tal como o mono estearato de glicerila, penta eritritol ou glicol de etileno. A decomposição do catalizador depois da redistribuição melhora a estabilidade da composição de policarbonato redistribuída.
