| 摘 要： | 采用小角Ｘ－射线散法测定大孔交联聚苯乙烯树脂的结构，发现大多数大孔交联聚苯乙烯在数纳米至数十纳米的标度尺寸范围内具有分形结构，分形维数介于２和３之间。本研究还进一步探讨了交联度、致孔剂，功能基化反应及后处理对大孔交联聚苯乙烯分形结构的影响。 |

| Abstract: | The structure of macroporous crosslinked polystyrenes was investigated by small angle X-ray scattering (SAXS). The results showed that fractal structure existed in most of these macroporous resins, and the values of fractal dimension D were ranging from 2 to 3 for the scaling parameters in the range from several nanometers to several ten nanometers. Analysis of the data confirmed that the fractal structure of macroporous crosslinked polystyrenes was determined by a lot of factors, such as crosslinking degree, porogenic agents, post treatments, functionalization and so on. |
| Keywords: | Crosslinked polystyrene Macroporous resin Fractal Fractal dimension Small angle X-ray scattering |
