figureThe plastic behaviour of polymers is also influenced by their morphology, or arrangement of molecules on a large scale. Stated simply, polymer morphologies are either amorphous or crystalline. Amorphous molecules are arranged randomly and are intertwined, whereas crystalline molecules are arranged closely and in a discernible order.
