Abstract

"PROCESSO PARA A PREPARAçãO DE UMA MISTURA". é apresentado um processo para a preparação de uma mistura de compostos de benzoxazolil-estilbeno pela reação de 4,4'-bis(benzoxazol-2-il) estilbeno não substituído com um o-aminofenol ou o-aminonaftol substituído para obter-se uma mistura compreendendo o 4,4'-bis(benzoxazol-2-il) estilbeno não substituído e pelo menos um 4,4'-bis(benzoxazol-2-il) estilbeno substituído, 4-naftoxazol-2-il-4'-benzoxazol-2-ilestilbeno e/ou 4,4'bis(naftoxazol-2-il) estilbeno. Estas misturas são úteis como agentes fluorescentes de iluminação e estabilizadores de luz para materiais poliméricos sintéticos como materiais têxteis de poliésteres, poliamidas e poliolefinas e artigos formatados.
