Structural disorder resulting from the statistical co-existence within the crystals of identical configurational units with different conformations.

Fig. Chain conformation of the disordered (above) and ordered (below) polymorphs of trans-1,4-polybutadiene (poly[(E)-but-1-ene-1,4-diyl]) in the crystalline state. The heavy black lines designate the double bonds and the symbols S+, S- and C the conformation.

Fig. Different possible conformations of cis-1,4-polyisoprene (poly[(Z)-2-methylbut-2- ene-1,4-diyl]) in the crystalline state, as viewed sideways along two orthogonal axes.
