Webthe crystal lattice composed of an orthorhombic unit cell with all bonds in a trans conformation as shown in Fig. 2(c). At the limit where all chains are stretched out and packed in the orthorhombic crystal lattice, we could attain the extended chain crystal (ECC) with its length parallel to the c axis ’ 20 mm for the given molecular weight.
