Syndiotactic polystyrene
- Theoretically, there are three structural forms of polystyrene that can be prepared from styrene monomer: atactic (phenyl rings randomly oriented about the polymer chain), syndiotactic (phenyl rings on alternating sides about the polymer chain), and isotactic (phenyl rings all on one side of the polymer chain).
- Syndiotactic polystyrene (SPS) is a new form of polystyrene polymer first synthesized in 1985 according to the claims of Idemitsu.
