A method for removing perfluorinated compounds from a fluoropolymer material is provided. The method includes the steps of: (a) providing the fluoropolymer material in a chamber; (b) providing an anaerobic environment in the chamber; and (c) providing a fluorination gas in the chamber, thereby exposing the fluoropolymer material to the fluorination gas. The method results in the removal the perfluorinated compounds from the fluoropolymer material.

Provided are a polymer having ultraviolet absorption functionality and preparation method thereof; specifically, three monomers having different ultraviolet absorption bands are used for copolymerization, achieving a significant expansion of the ultraviolet absorption range and achieving the effect of full-band ultraviolet shielding. The obtained polymer film has strong visible light transmittance, fluorescence, easy processing, excellent stability, and remarkable ultraviolet shielding performance, and can be broadly applied in such areas as aviation, construction, agriculture, and optical devices.

A method of producing at least one or more resins is disclosed. The method includes providing an amount of raw coal. The raw coal includes one or more impurities therein. The method also includes beneficiating the amount of raw coal to selectively removing at least a portion of some of the one or more impurities in the raw coal to form beneficiated coal. Additionally, the method includes processing the beneficiated coal to produce an amount of pitch. The method further includes modifying at least some of the pitch to produce the one or more resins. The one or more resins include a selected amount of a remainder of the one or more impurities that were not removed while beneficiating the amount of the raw coal, processing the beneficiated coal, and modifying at least some of the pitch.
