A crystalline domain usually limited by well-defined boundaries.
Polymer crystals frequently do not display the perfection that is usual for low-molar-mass
Twinned polymer crystals are, sometimes, erroneously referred to as 'crystals'.
Polymer crystals that can be manipulated individually are often called (polymer) single
