The syndiotactic polystyrene nanocomposite according to the present invention
has nano silicate materials dispersed individually in a styrene polymer matrix
by intercalation and exfoliation during polymerization. Besides, the syndiotactic
polystyrene nanocomposite according to the present invention is prepared by using
a catalytic system composed of a phyllosilicate-supported Group IVB transition
metal catalyst and alkylaluminoxane, wherein the phyllosilicate-supported Group
IVB transition metal catalyst comprises: a) a polymer, b) a phyllosilicate and
c) a Group IVB transition metal compound, and the polymer (a) is used as an insulating
material or media of the phyllosilicate (b) and the Group IVB transition metal
compound (c).
