Mesoporous melamine formaldehyde resins (MMF) with high surface areas and large pore volumes and diameters were prepared without the use of a template. Conditions such as solvent, concentration, formaldehyde/melamine ratio and curing temperature and time on the pore parameters of synthesized MMF were investigated. The results showed that the sample (MMF9-120) synthesized in the solvent H₂O/DMAc had the surface area higher than 1000 m²/g, pore diameter of about 22 nm and pore volume of about 3.5 cm³/g. It was found to be amphiphilic owing to the presence of amino, ether and alkyl groups on its surface, so that it adsorbed great amount of H₂O and toluene. Due to the large pore diameter and volume, it also adsorbed great amount of tannic acid (MW = 1701) and bovine serum albumin (MW = 69 k) (850 and 1160 mg/g, respectively), indicating an excellent adsorbent for large molecules. In addition, it was thermally stable and when heated at 350 °C, the formed MMF9-350 still possessed the high surface area (549 m²/g), which was expected to be a new resin support for catalysts, as compared to the traditional porous polystyrene resins which can only be used at temperatures below 120 °C.

在不使用模板的情况下，制备了具有高表面积，大孔体积和直径的中孔三聚氰胺甲醛树脂（MMF）。研究了溶剂，浓度，甲醛/三聚氰胺比，固化温度和时间等条件对合成MMF孔参数的影响。结果表明，在溶剂H ₂ O / DMAc中合成的样品（MMF9-120）具有大于1000m ² / g的表面积，约22nm的孔径和约3.5cm ³ / g的孔体积。由于其表面上存在氨基，醚和烷基，发现它是两亲的，因此它吸附了大量的H _2。O和甲苯。由于其较大的孔径和体积，它还吸附了大量的单宁酸（MW = 1701）和牛血清白蛋白（MW = 69 k）（分别为850和1160 mg / g），表明它是大分子的优良吸附剂。此外，它具有热稳定性，并且在350°C下加热时，形成的MMF9-350仍具有较高的表面积（549 m ² / g），相比于传统的MMF9-350 ，有望成为催化剂的新型树脂载体。传统的多孔聚苯乙烯树脂，只能在低于120°C的温度下使用。
