Description

technical field [0001] The invention relates to an active hydroxyl-containing polyarylether and its preparation method and application, belonging to the field of polymer synthesis. Background technique [0002] Polymers containing active groups such as hydroxyl, amino, and carboxyl groups are usually easier to modify their molecular structure due to the large number of reactive functional groups on their molecular chains, so as to achieve high performance and functionalization of polymers, such as amino groups. Polymers can use their amino groups and transition metals to form coordination bonds to achieve selective adsorption and removal of heavy metal ions; such as reacting Boc-anhydrides with amino-containing polymers, grafting Boc-anhydrides to the main chain of polymer molecules Among them, foamable polymers can be obtained, but such active group-containing polymers often have some shortcomings, and their heat resistance, mechanical properties, corrosion resistance, etc....

[0002] Polymers containing active groups such as hydroxyl, amino, and carboxyl groups are usually easier to modify their molecular structure due to the large number of reactive functional groups on their molecular chains, so as to achieve high performance and functionalization of polymers, such as amino groups. Polymers can use their amino groups and transition metals to form coordination bonds to achieve selective adsorption and removal of heavy metal ions; such as reacting Boc-anhydrides with amino-containing polymers, grafting Boc-anhydrides to the main chain of polymer molecules Among them, foamable polymers can be obtained, but such active group-containing polymers often have some shortcomings, and their heat resistance, mechanical properties, corrosion resistance, etc. are not good, such as carboxyl-containing polymers. Lactic acid, polymethacrylic acid, hydroxyl-containing polyvinyl alcohol, polyethylene glycol, amino-containing polyether amine, etc., have low glass transition temperature or melting point, and are difficult to be used in some high-temperature, highly corrosive environments.
