Abstract
In microcellular foaming process, the glass transition temperature (Tg) of polymer determines foaming temperature and has an effect on the other physical properties of polymer. In thisstudy, an evaluation of the current state of understanding for Tg was reviewed. Inaddition, we focused on the establishment and advancement of three main widely-used models that predict Tg (i.e. Chow model, Cha-Yoon model and Condo - Sanchez model). The comparisons of the three Tg-prediction models, with attention being given to their ownadvantages, disadvantages and scopes of application provide a reference for the further study.
