A highly efficient, spontaneous, and atom-economic polymerization of aroylacetylenes and amines at room temperature in air was established, and poly(β-enaminone)s with high molecular weights were produced in nearly quantitative yields. Moreover, singly E-configuration polymers can be obtained efficiently with secondary amines, while absolute Z-configuration products were prepared when using primary amines. In addition, the poly(β-enaminone)s can be degraded by primary amines in aqueous system to obtain definite compounds, proving their wide application prospects as degradable nitrogen containing polymers.
