A series of exo-7-thiabicyclo[2.2.1]hept-5-ene-2,3-dicarboximides were synthesized and polymerized using Schrock’s catalyst, 2,6-diisopropylphenylimidoneophylidene molybdenum(VI) bis(hexafluoro-tert-butoxide). The ring-opening metathesis polymerization (ROMP) reactions were found to proceed in a controlled manner, enabling chain extensions and tuning of polymer molecular weight. The polymers were characterized using size exclusion chromatography (SEC) as well as spectroscopic (NMR, FT-IR), thermal (TGA, DSC), and optical techniques. The physical, chemical, and optical properties of the polymers were found to be affected by the embedded sulfur atoms and the pendant substituents. Copolymers with norbornene were also synthesized and characterized. Treatment of a poly(thianorbornene) with potassium hydroxide led to ring-opening hydrolysis and afforded a derivative that was soluble in aqueous media.

Thianorbornenes 的开环复分解聚合


使用 Schrock 催化剂 2,6-二异丙基苯基吩基吩吩（VI） 双（六氟叔丁氧化物）合成了一系列外-7-噻双环[2.2.1]庚-5-烯-2,3-二羧腈胺并聚合。发现开环复分解聚合 （ROMP） 反应以受控方式进行，能够实现链延伸和聚合物分子量的调整。使用尺寸排阻色谱 （SEC） 以及光谱 （NMR， FT-IR） 、热 （TGA， DSC） 和光学技术对聚合物进行表征。发现聚合物的物理、化学和光学性质受嵌入的硫原子和悬垂取代基的影响。还合成了降冰片烯的共聚物并对其进行了表征。用氢氧化钾处理聚（硫代冰片烯）导致开环水解，并得到可溶于水性介质的衍生物。
