Mechanical Fabrication of Thermoplastic Polymers

Abstract: One of the most important features influencing the mechanical behavior of a fabricated thermoplastic item is the spatial arrangement of the polymer molecules. Znter aka processes developed for controlling the pattern of orientation of the polymer molecules are discussed.

“…The clustering tendency of benzene in oriented PS is greater than in unoriented PS. It is known that polymer chains are oriented in PS foams and that this orientation is a result of the expansion of the blowing agent bubbles . However, it is still not clear as to which molecular orientation arises during this process.…”

“…Surprisingly, crystals of phase A underwent heating-induced SCTSC transition and generated the crystals of phase B with thermoplastic bending behavior (bendable at to 240°C), a kind of mechanical property which is usually observed in linear polymers such as polyvinyl chloride, polystyrene, and polyoxymethylene. 38 To the best of our knowledge, organic single crystals exhibiting thermoplastic bending have not been well demonstrated.…”

“…The crystals of phase A exhibit elastic bending in the temperature range from 77 to 423 K. Heating the crystals to 433 K induces a single-crystal-to-single-crystal (SCTSC) phase transition, resulting in crystals of phase B that exhibit thermoplastic bending behavior (bendable at 393–513 K). Upon cooling below 393 K, the new shape of phase B can be retained, and the crystal can be reshaped when heated again above 393 K. This unique property is similar to those of linear polymers (e.g., poly­(vinyl chloride), polystyrene, and paraformaldehyde), allowing organic crystals of phase B to be morphed thermally to the desired shape. In addition, by measuring the optical waveguides of the bent crystals A and B , their potential application in flexible optical devices was assessed.…”
