Abstract: Non-isocyanate polyurethane (NIPU) monomer is firstly prepared through ring-opening reaction between propylene carbonate (PC) and ethylene diamine (EDA).Then NIPUA monomer with urethane bond (-NHCOO-) and C=C double bond both is synthesized by esterification between acryloyl chloride (AC) and end-hydroxyl of NIPU.The structure of products is confirmed by FT-IR and the synthesis process parameters are optimized by single-factor experiments.Addition polymerization is performed between the synthesized NIPUA monomer and butyl acrylate (BA),acrylic acid (AA) in the presence of benzoyl peroxide (BPO) and N,N-dimethylaniline (DMP),and a new urethane acrylate adhesive is prepared.IR spectra shows that this adhesive can be cured under certain conditions.The synthesis and cure process are optimized by single-factor experiments and the optimal conditions are found.
