Multi-component polymerization (MCP) based on hooz reaction is described. Under mild condition (0<sup>o</sup>C-40<sup>o</sup>C; catalyst-free), dialdehydes, bisdiazoketones and triethylboron engender the formation of Poly(β-hydroxyketone)s. The molecular weight (Mn) is up to 31.2kDa and the yield is up to 99%. The β-hydroxyketone structure in poly(β-hydroxyketone)s made its degradation under alkaline condition highly efficient with regeneration of dialdehyde for recycling. The β-hydroxyketone structure also provide a hydroxy group for various post modifications. Crosslinking and oxidation of poly(β-hydroxyketone)s were achieved. The crosslinked thermoset product is also degradable. The oxidized poly(β-Diketone)s provide a new strategy to synthesize diketonate-containing polymers, which can serve as polymeric ligands.
