Abstract
A composition comprising a polymeric crystalline structure having lamellae and/or multilamellar structures and that is devoid of any amount of amorphous material that is detectable by Scanning Electron Microscopy (SEM) with a magnification of ×2,300 at working distance of 10 mm and acceleration voltage of 15 kV. A novel method or preparation of the composition is also disclosed.

A composition comprising a polymeric crystalline structure having lamellae and/or multilamellar structures and that is devoid of any amount of amorphous material that is detectable by Scanning Electron Microscopy (SEM) obtained at a magnification of ×2300, a working distance of 10 mm, and an acceleration voltage of 15 kV.
A method of producing a crystalline polymer material, the method comprising:
- initiating growth of polymer crystals from a molten polymer;
- during said growth, immersing said polymer crystals and said molten polymer in a suitable extracting solvent, thereby extracting amorphous material;
- removing at least one polymer crystal from said solvent;
- and,
- removing residual adsorbed solvent from said at least one polymer crystal;
- thereby producing a final crystalline polymer material that is devoid of any amount of amorphous material that is detectable by SEM obtained at a magnification of ×2300, a working distance of 10 mm, and an acceleration voltage of 15 kV.
