Abstraet~Conformational energy calculations have been performed on two crystalline polymorphic forms of syndiotactic polypropylene. A chain conformation having the helicoidal s(2/1)2 symmetry has been obtained for the form of the polymer having chain axis c = 7.40 A.. A chain conformation having the
