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.
本发明公开了一种含有羧基的聚合物、其制备方法和应用、一种支撑催化剂及其制备方法以及戊烯抗生素中间体的制备方法。该聚合物具有较高的刚性和硬度,从而有效改善了聚合物的机械性能。同时,聚合物中以羧基为主官能团,并以羧基为载体,通过羧基与重金属的配位反应制备出金属与聚合物连接稳定性更好的支撑金属催化剂。上述两个因素可以提高支撑金属催化剂的稳定性,使催化剂可以循环使用而不会失去催化活性。同时,还可以减少重金属活性成分的损失,降低生产成本。
