Figure 1.Structures of metallocenes (in this case, zirconocenes). (a) Nonchiral structure produces atactic polypropylene. (b) Racemic mixture of this chiral structure produces isotactic polypropylene. (c) Cs-symmetric structure produces syndiotactic polypropylene. R = alkyl substitution [H, CH3, C2H5, C6H5]; X = bridge [CH2CH2, (CH3)2Si, (CH3)2C].
