研究了由合成的聚甲基丙烯酸丁酯PBMA和不含醇的芳香酯增塑剂液体组成的新型实验性组织调理剂的粘弹性能，以评估聚合物分子量的影响。根据不同温度下的粘弹性数据，绘制了储能模量G '、动态粘度η'和损耗角正切tan δ的主曲线。在低频范围内，聚合物分子量对粘弹性能G'和tan δ的影响尤为明显。然而，动态粘度η'对分子量并不十分敏感。这些结果表明，PBMA产生更理想的性能，组织调理剂，它是可能的，以制造新的材料没有酒精。
The viscoelastic properties of new experimental tissue conditioners which consist of synthesized poly (butyl methacrylate) PBMA and a liquid of aromatic-ester plasticizer, without alcohol, were investigated to evaluate the effects of the molecular weight of polymer. The master curves of storage modulus G', dynamic viscosity η' and loss tangent tan δ were constructed from the viscoelastic data at different temperatures. The effects of the molecular weight of polymer on the viscoelastic properties G' and tan δ were observed particularly, in a low frequency range. However, the dynamic viscosity η' was not very sensitive to the molecular weight. These results suggest that PBMA produces more desirable properties for tissue conditioners, and that it is possible to manufacture new materials without alcohol.
