| titleOfInvention | Process for making highly crystalline shaped part from pet or pen |
| abstract | A process for making a shaped part from a polymer selected from polyethylene terephthalate (PET) and polyethylene terephthalate (PET) and polyethylene naphthalate (PEN) by using a compacting tool comprising a die having a cavity and a punch having an outer surface. The process comprises the steps of: a) placing particles of the polymer in the cavity of the die heated to a compaction temperature, wherein the polymer has an intrinsic viscosity of at least 0.45 dL/g wherein the particles are a mixture of first particles with a particle size of 0.5-4000 μm and second particles with a particle size of 1000-4000 μm b) pressing the particles in the die cavity at a pressure of at least 3 MPa for 5-15 minutes while maintaining the temperature of the die at the compaction temperature and c) removing the shaped part from the die cavity. When the polymer is PET, the compaction temperature is 235-259° C. When the polymer is PEN, the compaction temperature is 250-275 ° C. |
