Syndiotactic polystyrene (sPS) is a newly crystal engineer plastics. Compared with atactic polystyrene

it has perfect properties

such as high thermal resistance temperature

high crystallization velocity and chemical resistance. So the research on sPS has carried out recently. In this paper

structure

properties and chemical modification methods were discussed

which including the introduction of functional group (sulfonation

halogenation

maleic anhydridition) to molecular chain of sPS

copolymerization of sPS with other olefin monomers.
