Stable conformations of polymer chains and model compound molecules

In order to have information about the conformational energy of polymer chains, the structures of small molecules which have chemical configurations similar to those of polymer chains are studied. The results for polyethylene, poly(vinylchloride), polypropylene, 1,4-polyisoprene, 1,4-polybutadiene, nucleic acid and polypeptides show that the conformations of small model molecules are closely correlated with those of polymer chains.
