In order to modify the dense of the hydrophilic groups of the superabsorbents, as well as reutilize wast polymer , a rigid and hydrophobic polystyrene chain have been introduced into the superabsorbent, and novel superabsorbent nanocomposites based on partially neutralized acrylic acid, waste polystyrene foam and sodium type montmorillonite powder have been synthesized. The properties of the superabsorbents, effects of various main factors on water absorbency have been systemically investigated. The structure, surface morphology and thermal stability of the composites were characterized by FTIR, XRD, SEM and thermo gravimetric analysis.

The lowest surface tension of N_xB solution was better at 25℃, and lowest surface tension would down with carbon . cmc( critical micelle concentration) and γ_ in N_(12)B are 4.1 × 10~(-4)mol/L, 24.5 mN.m~(-1),what was smaller than LAS . The cmc of N_(12)B- NaCl are down with NaCl up.The surface tension and cmc of N_(12)B and N_(16)B are higher than that of N_(12)OB and N_(16)OB because of hydrophilic group ,but that of N_(12)B is lower than that of N_(16)B because of hydrophobic group .5. The borate structure and semipolar bond were studied in different pH by infrared spectrum .It indicated that N_xB and N_xOB have not semipolar bond at pH
4、25℃,N_xB系列都有较低的表面张力,并随碳原子数的增加而最低表面张力下降。N_(12)B比同碳原子数的十二烷基苯磺酸钠的最低表面张力34.5mN/m低,且临界胶束浓度为4.1×10~(-5)mol/L,也比LAS低,且随着NaCl浓度的增加而略有下降,比较N_(12)B和N_(16)B,由于C_(16)疏水基的异构体使N_(12)B的临界胶束浓度和临界胶束浓度时的表面张力γ_(cmc都低,由于增加了亲水基团使得N_(12)OB和N_(16)OB的表面张力和临界胶束浓度都要高于N_(12)B和N_(16)B。
