Abstract

AbstractSingle crystal growth and chain folding behaviour of two polyalkenamers (polydecenamer and polydodecenamer) have been examined. They form chain folded lamellar single crystals in spite of the macrocyclic nature of the molecules. The fold length could be varied continuously by the crystallization temperature and by annealing. In the former case the fold length depended on the supercooling which amongst others was also determined by the cis double bond content in an expected manner. Incorporation of cis double bonds within the lattice is inferred.
