Cold drawing: Essentially, it is a deformation caused by high-elastic deformation; such large deformations cannot be reversed at room temperature, but can return to their original state when heated. 2. Swelling ratio Q: The ratio of the volume of a cross-linked polymer at swelling equilibrium to its volume before swelling. 3. The multidimensionality of glass transition: Tg is merely an indicator for determining the glass transition; the glass transition can also be observed by keeping the temperature constant and changing other factors. 4. Polymer solution: A homogeneous polymer formed when polymers are dispersed in a solvent in molecular form. 5. Ideal solution: refers to a solution in which the interaction energies between solute molecules, between solvent molecules, and between solute and solvent molecules are all equal ； There is no change in volume during the dissolution process.
