利用SEC-MALLS系统对木质素酚和常规木质素的分子形态进行了分析。MALLS分析已被用作聚合物绝对分子量的方法。然而，由于木质素结构的复杂性和分散性，使得木质素的绝对分子量难以测定。但MALLS法和传统的线性聚苯乙烯标准校正法测定的木质素分子量的差异可以反映木质素分子形态的差异。与其它木质素相比，木酚树脂的分子形态更宽、更线性。这一特性与木质素酚具有其它木质素所不具有的热塑性有关。
The molecular morphology of lignophenol and conventional lignins were analyzed with SEC-MALLS system. MALLS analysis has been used as method for absolute molecular weight of polymers. However determination of absolute molecular weight of lignin is difficult due to divisively and complication of lignin structure. But the difference in the molecular weight of lignin determined by MALLS and conventional calibration methods using linear polystyrene standard can show the difference of molecular morphology of lignin. The molecular morphology of lignocresol was more spreading and linearity, compared with other lignins. It was suggested that this characteristic of lignophenol is concerned with thermoplasticity of lignophenol that other lignins do not have.
