A new type of comonomer EDA-di(diacetone propionamido) was synthesized by the Michael addition reaction using diacetone acrylamide and ethanediamine as raw materials.The structure of the monomer was verified by 1H NMR and 13C MNR.Polyurethane dispersions(PUDs) were synthesized by the prepolymerization process using polyneopentanediol adipate(PNA) as soft segment
isophorone diisocyanate(IPDI) as hard segment
dimethylolpropionic acid(DMPA) as hydrophilic monomer
EDA-di(diacetone propionamido) as functional monomer.Research was done to know the influence of monomer on polyurethane dispersions.The result showed that particle size increased as the content of monomer increased while viscosity decreased.The mechanical property was improved through the room temperature self-crosslinking of adipic dihydrazide(ADH).
