In view of possible applications of `push‐pull' acetylenes 1 and `push‐pull' olefins 2 as potential non‐linear optics materials, synthetic attempts towards polymers of type 4 and 6 ( Scheme 2 ) have been undertaken. Two so far unknown `push‐pull' acetylenes 1a , b with R=styrene, have been prepared under carefully controlled conditions which quite surprisingly fail to give polymers 4a , b by anionic or radical‐induced polymerization. On the other hand, `push‐pull' acetylenes may be reacted with commercially available poly(4‐vinylphenol) to give polymers 6c , d with a 40 – 70% conversion of phenol units.
