Conformational and packing energy calculations have been performed on the ~t modification of syndiotactic polystyrene. The conformational energy has been optimized as a function of the internal parameters of the chain. The packing energy has been calculated considering at first the best packing of c

Molecular mechanics methods have been used in order to find the conformations of various syndiotactic polymers in crystals. Three different classes of polymers have been examined: i) polyolefins, such as poly(propylene), polystyrene, poly(1-butene) and poly(1,2-butadiene); ii) polydienes, such as ci

## Abstract Summary: The vast majority of head‐to‐tail stereoregular crystallizable polymers with an isotactic structure generally assume a helical symmetry in the crystalline state, compatible with the regular repetition along the chain axis of isomorphous isoclined units. There are at least two c
