21. PEKK's glass transition temperature ( Tg ) is 162�C. 22. As soon as the metal is cooled below the appropriate transition temperature , it becomes superconducting. 23. Transition temperature can also be affected by the degree of unsaturation of the lipid tails.24. Materials are only dielectric above their corresponding transition temperature . 25. Polymers have both a melting temperature T m and a glass transition temperature T g. 26. Relatively strong intermolecular forces in semicrystalline polymers prevent softening even above the glass transition temperature . 27. For example, the Morin transition temperature of hematite decreases with a decrease in the particle size. 28. Above the transition temperature the structure is cubic and symmetric, causing the material to become dielectric. 29. These include glass transition temperature , viscosity, and stiffness. 30. Properties such as the phase transition temperature and unit cell sizes vary smoothly with the composition.
