Polymer containing carboxyl group, preparation method and application thereof, supported catalyst and preparation methods thereof and preparation methods of penem antibiotic intermediate
A polymer containing a carboxyl group, a preparation method and an application thereof, a supported catalyst and a preparation method thereof and preparation methods of penem antibiotic intermediate are disclosed. The polymer has high rigidity and hardness, thus the mechanical properties of the polymer is effectively improved. Meanwhile, in the polymer, the carboxyl group is used as a main functional group, and is used as a carrier to prepare, by means of a coordination reaction between the carboxyl group and a heavy metal, a supported metal catalyst which has better connection stability between the metal and the polymer. The above two factors can improve the stability of the supported metal catalyst, such that the catalyst can be recycled without losing the catalytic activity. Meanwhile, loss of a heavy metal active ingredient and production cost can be reduced.

METAL ORGANIC FRAMEWORK (MOF) STRUCTURED OBJECT AND METHOD
A method of making a metal organic framework (MOF)-polymer composite material includes forming a homogeneous solution comprising a solvent, a metal salt, a polymer which is soluble in the solvent, and a reactant which can be synthesized to provide an organic linker during formation of a MOF structure, synthesizing the homogeneous solution to crystallize a MOF structure in the homogenous solution to yield the MOF structure distributed in a remainder solution, applying an antisolvent to the remainder solution with the MOF structure distributed in the remainder solution to form a polymer-rich phase, where the MOF structure is integrated into the polymer matrix during forming of the polymer matrix to produce a MOF-polymer composite material. The MOF-polymer composite material can be formed on a substrate to produce a MOF structured object, which can be a membrane, film, or other object.
