Polymer fatliquor agents were synthesized with hydrophobic monomer fatty alcohol maleic monoester and hydrophilic monomer acrylic acid by free radical water solution polymerization in which more active monomer was supplemented in batches. The influence of reaction conditions on the conversion rate of monomers was studied such as neutralization degree, the kinds of hydrophilic monomer and the chain length of aliphatic alcohol. The structure of dodecanol maleic monoester-acrylic acid copolymer was characterized by FT-IR. The results showed that, when the neutralization degree is 90%, dropping time of acrylic acid is 1.5 h, reaction temperature is 85℃, reaction time is 2h, the mass fraction of initiator ammonium persulfate is 8% (base on total mass of reaction materials), the conversion rate of dodecanol maleic monoester is 75.16%.
