Abstract

Patente de Invenção: <B>"REDISTRIBUIçãO DE POLIFENILENO éTERES E POLIFENILENO éTERES COM NOVA ESTRUTURA"<D>. A presente invenção refere-se à distribuição de polifenileno éteres por reação do polifenileno éter em solução com um composto fenólico, onde são usados compostos fenólicos especiais. A reação de redistribuição pode ser realizada em tolueno ou em misturas de tolueno/álcool. A reação pode ser realizada na presença ou ausência de um catalisador. Usando-se um processo para a redistribuição de polifenileno éteres por reação do polifenileno éter em solução com um composto fenólico, onde o polifenileno éter é reagido com um composto fenólico de fórmula 3, onde os anéis fenólicos são distribuídos com grupos metila ou grupos etila nas posições orto, e o grupo X é separado do anel fenólico através de pelo menos dois átomos de carbono, e o composto fenólico tem um peso molecular não-superior a 400 g/mo, de preferência não superior a 300 g/mol, e a redistribuição é realizada em uma mistura de tolueno e metanol com 1 - 30% em volume ou em tolueno na presença de um catalisador de transferência de fase, tal como cloreto de tri(alquil C8 - C10) metil amónio como promotor, e um difenoquinona, de preferência 3,3',5,5'-tetrametil-4,4'-difenoquinona, é usada como catalisador e a concentração molar do composto fenólico é escolhida entre 0,9 e 1,1 vezes a quantidade molar de unidades monoméricas no polifenileno éter na solução reacional, mais de 90% de composto fenólico podem ser incorporados no polifenileno.
