As a popular alkyne\u2010based MCP, the A\n                    <jats:sup>3<\/jats:sup>\n                    \u2010polycouplings of alkynes, aldehydes, and amines are developed for the synthesis of poly(propargylamine)s under the catalysis of metal catalysts. In this work, through the design of carboxylic acid group\u2010activated alkyne monomers, a catalyst\u2010free, four\u2010component polymerization of propiolic acids, benzylamines, organoboronic acids, and formaldehyde is reported under mild condition at 45\u00a0\u00b0C in dichloroethane. This four\u2010component polymerization is applicable to different monomer structures, which can afford seven poly(propargylamine)s with up to 94% yields and molecular weights of up to 13\u2009900\u00a0g\u00a0mol\n                    <jats:sup>\u22121<\/jats:sup>\n                    . Moreover, the poly(propargylamine)s demonstrate good solubility and processibility, high thermal stability and light refractivity, unique photophysical property, and so on. The simple monomers, mild condition, low cost, high efficiency, and procedure simplicity of this catalyst\u2010free four\u2010component polymerization demonstrates an elegant example of functional polymer synthesis.\n
