Aliphatic polyamides (nylons): Interplay between hydrogen bonds and crystalline structures, polymorphic transitions and crystallization

Aliphatic polyamides (nylons) constitute a family of polymers with outstanding properties and multiple applications. Despite the intensive research studies carried out nylons, there are still unsolved questions concerning crystallization processes, crystalline structures, polymorphic transitions, morphologies. Constrains imposed by strong intermolecular interactions affect amorphous state, rigid phase, molecular folding, morphology obviously structure. Some these relevant points discussed in present work.
