摘　　要：合成了丙烯酸十六酯(HA)与丙烯酸(AA)的共聚物凝胶,研究了共聚组成对共聚物凝胶性能的影响。结果表明:经二甲亚砜(DMSO)平衡溶胀后的凝胶,在HA与AA的物质的量比为1∶1时,具有较高的规整性。溶剂的极性对聚合物凝胶的规整性有较大的影响。DSC及X射线衍射表明共聚物凝胶具有液晶性能。Crosslinked Copplymer gels were perpared by copolymerization of hexadecyl acrylate(HA)and acrylic acid(AA).The effects of composition of monomers on the properties of the gels were studied.The poly(HAcoAA)gel with HA∶AA=1∶1(molar ratio)exhibited the highest ordered structure in dimethylsulfoxide(DMSO).The polarity of solvent showed a greater effect on the ordered structure of the gels.The organized liquid crystalline structure was proved by differential scanning calorimetry (DSC) and Xray diffraction(XRD)
