Aj. Waddon, THE EFFECT OF HIGHLY SPECIFIC LATTICE HYDROGEN-BONDING ON MORPHOLOGIES OF SOLUTION-GROWN CRYSTALS, Journal of polymer science. Part B, Polymer physics, 35(8), 1997, pp. 1175-1183
Morphologies of solution-grown crystals in systems containing strong a
nd specific intralattice hydrogen bonding (nylons) are compared with s
ystems displaying only van der Waals intracrystal attractions. The lat
ter are shown to produce crystals that clearly mirror the underlying c
rystallographic symmetry; in the former systems the morphologies are m
uch more complex and disorganized. This difference is discussed in ter
ms of intralattice forces affecting growth rates and chain rearrangeme
nt during crystallization. Arguments deriving from differences in lame
llar thickening behavior are also used to demonstrate this point. (C)
