      Glass Transition Temperature (Tg) of Plastics - Omnexus

      The glass transition temperature (Tg) is a phenomenon of amorphous polymers. At this temperature, polymers undergo a transition from glassy to rubbery state. Tg is an important feature of polymer behavior. It marks a region of dramatic …

      Glass Transition Temperature (Tg) of Polymers

      What is Glass Transition Temperature (Tg)? Glass transition temperature is the temperature at which an amorphous polymer changes from a hard/glassy state to a soft/leathery state, or vice versa. Tg is directly related to a material’s …

      What is TG of a polymer?
      Tg depends on the chemical structure of the polymer defined by its crystallinity. They may be amorphous, crystalline or semi-crystalline. Amorphous polymers have a random molecular structure. At Tg, they take the glassy-state properties like brittleness, stiffness, and rigidity (upon cooling). They have a lower Tg than semi-crystalline polymers.

      Which polymer has a TG/TM ratio?
      materials frequently exhibit a Tg even if the polymer is semi-crystalline and not totally amorphous. As a rule of thumb, most polymers will have a ratio of Tg/Tm of between 0.50 and 0.75, where Tm is the polymer's melting point (°K). The glass transition temperature exhibited by a polymer is dependent upon the chemical make-up of the material.

      What is TG in chemistry?
      What is Tg? Tg is the accepted abbreviation for the glass transition temperature. All amorphous (non-crystalline or semi-crystalline) materials will yield a Tg during heating and Tg is the main characteristic transformation temperature of the amorphous phase.

      Why does a block copolymer exhibit two TG's during heating by DSC?
      When reporting the Tg of a the two different polymers. Each phase will exhibit its own distinct Tg. Thus, if the Tg's of the two polymers are different enough, the block copolymer material will exhibit two Tg's during heating by DSC. Random copolymers are those which consist of random alternating blocks along the main polymer chain.

      How does glass transition temperature affect a polymer's molecular structure?
      The glass transition temperature (Tg) is a key property that dictates the applicability of conjugated polymers. Here the authors use one adjustable parameter to build a relationship between the Tg and the molecular structure of semiflexible polymers that differ in aromatic backbone and alkyl side chain chemistry.

      What is TgAb of a random copolymer?
      The monomers are chosen in such a way that the Tg values of the respective homopolymers, TgA and TgB, lie above and below the glass transition temperature which has to be checked. In general, TgAB of the random copolymer lies between TgA and TgB. The actual TgAB value depends, however, on the ratio A/B.
