Notes:
Morphologies of solution-grown crystals in systems containing strong and specific intralattice hydrogen bonding (nylons) are compared with systems displaying only van der Waals intracrystal attractions. The latter are shown to produce crystals that clearly mirror the underlying crystallographic symmetry; in the former systems the morphologies are much more complex and disorganized. This difference is discussed in terms of intralattice forces affecting growth rates and chain rearrangement during crystallization. Arguments deriving from differences in lamellar thickening behavior are also used to demonstrate this point. © 1997 John Wiley & Sons, Inc. J Polym Sci B: Polym Phys 35: 1175-1183, 1997
