Which polymer has the highest glass transition temperature?

The glass transition temperature is the reversible transition in amorphous materials or in amorphous regions within semicrystalline materials from a hard and relatively brittle state into a molten or rubber-like state. The glass transition temperature of polymethyl methacrylate is 105 ^oC. The glass transition temperature of polyvinyl alcohol is 85 ^oC. The glass transition temperature of polyvinyl chloride is 80 ^oC. The glass transition temperature of polyethylene terephthalate is 70 ^oC. The glass transition temperature of poly carbonate is 145 ^oC. Hence, poly carbonate has the highest Tg.
