Water-soluble rosin monomer N-methyl-N, N-divinyl-3-dehydroabietoyloxypropan-1-ammonium bromide(DMDHAE) was prepared from dehydroabietic acid, 3-bromopropanol and methyldiallylamine, and its structure was characterized by nuclear magnetic resonance(NMR), gas chromatography(GC), elemental analysis, FT-IR, mass spectrometry(MS) and melting point instrument. The results indicated that the purity of monomer was 91%, melting point was 127-131 ℃, and solubility was 1.50-1.60 g/mL; characteristic group peaks were appeared in the NMR and FT-IR spectra, and the mass spectrometry and elemental analysis results were consistent with the theoretical value. The self-polymerization parameter was measured by differential scanning calorimeter(DSC), and self-polymerization kinetics was analyzed with autocatalytic model. The results showed that DMDHAE was polymerizability, the activation energy(Ea) was 124.336 kJ/mol, and mechanism function f(α) was SB(m, n) model.
