AbstractA rigid silica colloidal crystal template was formed by self-assembly of the monodispersed silica dispersion prepared according to Stober method. Within the interstitial void of the template, beta-diketonate titanium complexes[ (dbm)(3) Ti (OPh) /MAO] catalyzed polymerization of styrene was carried out to form syndiotactic polystyrene (sPS) /silica composites. The titled ordered macroporous syndiotactic polystyrene was achieved by chemical decomposition of the silica template with concentrated aqueous hydrofluoric acid, which was confirmed by SEM results. FTIR spectra indicated that all silica was removed from the composites in this study. DSC revealed that the as-prepared macroporous sPS was significantly different from the bulk one, and the unique properties were inherent rather than from the enforcement effect by the silica template. Further investigation concerning the inherent microstrucutures about the molecular weight and its distribution, tacticity of the styrene etc. and their dependence on the confinement is in progress.
