Hydrophobical monomer N,N-diallyl-N-hexadecylamine was synthesized by the reaction between diallyamine and 1-bromohexadecane.The monomer was characterized using FTIR,¹H NMR and element analysis.A series of hydrophobically modified pH sensitive intelligent hydrogels poly(2-hydroxylethyl methacrylate/sodium acrylate/N,N-diallyl-N-hexadecylamine)[P(HEMA-NaAA-DiAC₁₆)]was successfully prepared by radically micellar copolymerization with 2-hydroxylethyl methacrylate(HEMA),sodium acrylate(NaAA),and N,N-diallyl-N-hexadecylamine(DiAC₁₆) as comonomers,sodium dodecyl sulfate(SDS) as the surfactant,N,N'-methylenebisacrylamide(BIS) as crosslinking agent,ammonium persulfate[(NH₄)₂S₂O₈]-N,N,N',N'-tetramethylethylenediamine(TMEDA) as initiating agent.The effects of hydrophobical monomer,NaAA,BIS contents and pH,ionic strength on swelling behaviors of P(HEMA-NaAA-DiAC₁₆) had been studied.The results indicate that the equilibrium swelling ratio SR₀ of the hydrogels decreases with increasing the amounts of DiAC 16 or BIS,with decreasing of NaAA,which are 78.9~163.91 in distilled water.The n values are 0.5~1.0 and increase with the increase of DiAC 16,NaAA or BIS.The diffusions of water into P(HEMA-NaAA-DiAC₁₆) gels are found to be a non-Fickian mode and exothermic process.The ΔH_m are -2.09~-3.64 kJ/mol,the modulus of ΔH_m and affinity between the polymers and water increase with the increase of NaAA and BIS,and the decrease of DiAC₁₆.The equilibrium swelling ratio decreases with the increase of ionic strength.
