Cover: The figure shows the map of the conformational energy of syndiotactic 1,2‐poly(1,3‐butadiene) in the crystalline field as a function of the two independent torsion angles in the main chain. The loci of the points corresponding to the helical s(2/1)2 symmetry of the chain and the point corresponding to the t cm symmetry are also shown. Energy maps have been calculated also for various vinyl polymers deriving from 1,3‐diene monomers in order to predict the values of the conformational parameters for each polymer. Further details can be found in the Full Paper by B. Pirozzi, * R. Napolitano, and S. Esposito on page 679.
