| Abstract: | The structure of stereoregular polymers of 1,3-pentadiene was determined by 13C-NMR spectroscopy at 22.6 MHz. Not only was it possible to distinguish between cis-1,4 and trans-1,4 but also between isotactic and syndiotactic cis-1,4 structures. Triad effects were detected in the trans-1,2 syndiotactic polypentadiene; 1,4–1,2 as well as 1,4–4,1 linkages were observed. |
