The resulting milled powder is characterized by molecular weight measurements, differential scanning calorimetry and wide-angle X-ray scattering. Regardless of the initial degree of crystallinity or milling temperature employed, MM apparently yields an “oriented amorphous” PET morphology in which the PET chains are locally aligned but rotationally disordered. This conclusion is based on the persistence of the (100) peak in otherwise amorphous x-ray patterns from milled PET. Thermograms of milled PET exhibit a small, broad crystallization exotherm and a large melting endotherm. The unusually small crystallization enthalpy is attributed to the local orientation of PET molecules present in the oriented amorphous morphology. Only minor rotations and translations of oriented PET molecules are needed to put the chains into register and, hence, the crystalline state. Evidence is also presented to suggest that extended-chain crystals of PET are produced upon crystallization of mechanically milled PET.}, number={19}, journal={POLYMER}, author={Bai, C and Spontak, RJ and Koch, CC and Saw, CK and Balik, CM}, year={2000}, month={Jun}, pages={7147–7157} } @article{smith_bai_ade_spontak_balik_koch_1998, title={X-ray microscopy characterization of a thermoplastic / liquid crystalline polymer blend produced by mechanical alloying}, volume={19}, DOI={10.1002/marc.1998.030191104}, abstractNote={Incorporation of liquid crystalline polymers (LCPs) into commodity polymers remains a challenge in the design of high-performance, low-cost polymeric blends. Blends of a thermoplastic polymer and a nematic LCP are produced here by mechanical alloying. Functionality sensitive X-ray microscopy reveals LCP dispersions as small as 100 nm in diameter. Intimate mixing remains upon subsequent melt processing, indicating that mechanical alloying is suited for applications such as recycling.}, number={1998}, journal={Macromolecular Rapid Communications}, author={Smith, Andy and Bai, C. and Ade, H. and Spontak, Richard and Balik, C.
