from 206 °C to 168 °C and 433 °C to 382 °C as the mol% of the chromophore-substituted monomer was increased. UV–vis absorbance spectroscopy was used to quantify the chromophore content. A close correlation (68–95%) between the measured and calculated absorbance was found. The polymer containing 22.92 mol% of the chromophore-substituted monomer had a maximum r33 of 70 pm/V when polled at an optimum
使用Grubbs第三代引发剂通过ROMP合成了侧链EO共聚物系列,并用乙基乙烯基醚淬灭。通过结合两种降冰片烯-二芳基酰亚胺单体,一种具有环己基取代基,另一种被FTC发色团取代来制备共聚物。发色团取代的单体的mol%在0.00mol%至22.92mol%之间变化,以83-92%的产率和97-98%的纯度获得所有聚合物。该顺:反式亚乙烯基比例保持恒定在1:1,这证明聚合物是无定形的。峰值分子量从29,541 g / mol增加到142,113 g / mol,PDI从1.36增加到4.01。随着生色团取代单体的摩尔%增加,玻璃化转变和热分解温度从206°C降至168°C,从433°C降至382°C。紫外可见吸收光谱用于定量发色团含量。发现测得的吸光度与计算的吸光度之间有密切的相关性(68–95%)。包含22.92 mol%发色团取代的单体的聚合物的最大r 33当在200°C的轮询温度下以60 V
