Abstract
"MéTODOS PARA TRATAR POLIéSTER, PARA RECUPERAR POLIéSTERES QUE CONTENHAM CONTAMINANTES E/OU IMPUREZAS, E PARA PARTìCULAS DE POLIéSTER NO ESTADO SóLIDO" Um método para tratar poliésteres compreende combinar partículas separadas de um poliéster com uma composição alcalina tal que a composição alcalina cubra as partículas de poliéster. As partículas são então aquecidas em um ambiente que seja pelo menos substancialmente isento de água. O método pode ser eficazmente usado para limpar, descontaminar e até aumentar a viscosidade intrínseca dos materiais de poliéster. Além disso, quando usado na recuperação de materiais de poliéster contendo contaminantes e/ou impurezas, o método pode fornecer um produto de poliéster superior, tanto em termos de viscosidade intrínseca quanto de cor.
