POLYMER CONTAINING CARBOXYL GROUP, METHOD FOR PREPARING SAME AND USE THEREOF, METHOD FOR PREPARING SUPPORTED CATALYST AND PENEM ANTIBIOTIC INTERMEDIATES

摘要

The present invention discloses a polymer containing a carboxyl group, a method for preparing same and a use thereof, and a method for preparing a supported catalyst and a penem antibiotic intermediate. The polymer is made by polymerizing three monomers with different structures. The carboxyl group-containing polymer is a crosslinked polymer, and the polymer chain contains a large number of phenyl rings, and which can improve the rigidity and hardness of the polymer, thus effectively improving the mechanical properties of the polymer. Meanwhile, in the polymer, the carboxyl groups are used as the main functional groups, and are used as a carrier to prepare a supported metal catalyst, by means of a coordination reaction between the carboxyl groups and heavy metals, which has a 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 the loss of the catalytic activity. Meanwhile, they are also able to reduce the loss of the heavy metals active ingredients and reduce production costs.
