    摘要： A method for reducing the concentration of poly(aryl ether ketone) in an original polymer composition that is exposed to an aggressive chemical environment that is more aggressive against poly(biphenyl ether sulfone) than it is against the poly(aryl ether ketone) while maintaining or exceeding at least one of the original polymer composition's tensile strength, tensile modulus, flexural strength and flexural modulus retention ratio after exposure to the aggressive chemical environment.
