23. The reason for the relatively low molecular weights of the resulting polymers has not been sufficiently clarified yet.
24. 1H-NMR spectra of model compounds (3a and 4a) were analogous to those of polymers in the cis/trans ratio as well as their constitution.
25. Both 3a and 4a were amorphous during both heating and cooling processes.
26. Thermogravimetric analysis (TGA) showed that the polymers had good thermal stability. For example, heating 3 to 400 °C (20 °C/min) gave a weight retention of 83 % with the onset of weight loss at approximately 350 °C.
