It is an amorphous polymer with a softening temperature of about 100℃. The atactic polystyrene is polymerized from radical polymerization, or ionic polymerization. Isotactic polystyrene was obtained by Natta in 1955 with Ziegler-Natta catalyst. It is highly crystalline, with a melting temperature of 240℃. However, its crystallization rate is too slow, to make any commercial application of this material viable. Syndiotactic polystyrene is also a highly crystalline polymer, with a melting temperature of about 270℃. More important thing is , its crystallizatin rate is very fast.
