The high-pressure crystallized poly(ethylene terephthalate) samples were investigated with scanning electron microscopy. The striation appearance, which is the most common feature of polymer extended-chain crystals, was clearly observed. Poly-(ethylene terephthalate) extended-chain crystals with thi

Pressure effect on the melting behavior of poly(butylene terephthalate) (PBT) and poly(hexamethylene terephthalate) (PHT) was studied by high-pressure DTA (HP-DTA) up to 320 and 530 MPa, respectively. Cooling rate dependence on the DSC melting curves of the samples cooled from the melt was shown at
## Abstract The effect of pressure on the crystallization of poly(ethylene terephthalate) (PET) was studied. The Instron capillary rheometer was adapted as a high‐pressure/high‐temperature dilatometer to carry on experiments up to 40,000 psi. Isothermal measurements of PET melt density were made wi
