The dilute solution properties of a sample of high molecular weight rosin substituted hydrogenated polynorbornene (hPDNB) homopolymer, prepared via ROMP and post-polymerization modified by backbone hydrogenation, was investigated by the online measurement of intrinsic viscosity, refractive index, two-angle light scattering and size exclusion chromatography (SEC) in tetrahydrofuran (THF) at 35 °C. The weight average molecular weight ($\bar{M}$_w), intrinsic viscosity ([η]), radii of gyration ($\bar{R}$_G) and hydrodynamic ($\bar{R}$_H) radii, and concentration of the polymer fractions obtained from corresponding traces of the chromatograms. From these data, the double logarithmic plots of $\bar{M}$_w versus [η], $\bar{M}$_w versus $\bar{R}$_G and $\bar{R}$_H, and $\left[\eta \right]{\bar{M}}_w^{-\mathrm{½}}$ versus ${\bar{M}}_w^{\mathrm{½}}$ scaled the dimensions of the polymer chains to molar mass. The results, surprisingly, indicated that the rosin-substituted poly(norbornene) is flexible like poly(methyl acrylate). To confirm the results, the data were analyzed by the worm-like touched-bead model which predicated the polymer to be more rigid than poly(methyl acrylate) but less rigid than hindered poly(di-alkyl phenyl acrylate) and poly(di-tert-butyl fumarate).

通过在线测量特性粘度、折射率、两角光散射，研究了通过ROMP制备并通过主链氢化改性的后聚合的高分子量松香取代的氢化聚降冰片烯(hPDNB)均聚物样品的稀溶液性质。和尺寸排阻色谱 (SEC) 在四氢呋喃 (THF) 中 35 °C。重均分子量（$\overline{米}$_w )、特性粘度 ([η])、回转半径 ($\overline{\mathrm{电阻}}$_G ) 和流体力学 ($\overline{\mathrm{电阻}}$_H ) 半径，以及从相应的色谱图谱中获得的聚合物级分的浓度。从这些数据，双对数图$\overline{米}$_w对 [η]，$\overline{米}$_w对$\overline{\mathrm{电阻}}$_摹和$\overline{\mathrm{电阻}}$_H , 和$\left[\eta \right]{\overline{米}}_{瓦}^{-\mathrm{½}}$ 相对 ${\overline{米}}_{瓦}^{\mathrm{½}}$将聚合物链的尺寸按摩尔质量缩放。结果令人惊讶地表明，松香取代的聚（降冰片烯）与聚（丙烯酸甲酯）一样具有柔性。为了证实结果，通过蠕虫状接触珠模型分析数据，该模型预测聚合物比聚（丙烯酸甲酯）更刚性，但比受阻聚（二烷基苯基丙烯酸酯）和聚（二-富马酸叔丁酯）。
