在不使用模板剂的情况下制备了具有高比表面积、大孔容和孔径的介孔三聚氰胺甲醛树脂（MMF）。研究了溶剂、浓度、甲醛/三聚氰胺比、固化温度和固化时间等条件对合成的MMF孔参数的影响。结果表明，以H2O/DMAc为溶剂合成的样品（MMF 9 -120）比表面积大于1000 m2/g，孔径约为22 nm，孔容约为3.5 cm 3/g。由于其表面存在氨基、醚基和烷基基团，使其具有两亲性，从而对水和甲苯有较强的吸附作用。由于大的孔径和体积，它也吸附大量的单宁酸（MW = 1701）和牛血清白蛋白（MW = 69 k）（850和1160 mg/g，分别），表明一个优秀的吸附剂的大分子。此外，它是热稳定的，并且当在350 °C下加热时，所形成的MMF 9 -350仍然具有高表面积（549 m2/g），与只能在低于120 °C的温度下使用的传统多孔聚苯乙烯树脂相比，这有望成为用于催化剂的新型树脂载体。
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.
