Description

technical field [0001] The invention relates to the technical field of isonitrile compounds, in particular to a polyisourea polymer and its preparation method and application. Background technique [0002] Isonitrile compounds are one of the chemical raw materials that are easy to obtain or synthesize. The use of isonitrile to construct functional polymers has important academic and technical significance, and has attracted widespread attention of scientists. At present, isonitrile-based small molecule reactions have flourished and have been widely used in biology, medicine, materials and other fields. In the past few decades, scientists have done a lot of research on its reaction mechanism, catalytic system and application, such as Passerini three-component reaction and Ugi four-component reaction (Boyarskiy V.P., Bokach N.A., Luzyanin K.V. , et al.Chem.Rev.2015,115,2698-2779.; Domling A.,Wang W.,Wang K.Chem.Rev.2012,112,3083-3135.;DmlingA..Chem.Rev.2006 , 106, 17-89.; Sa...
