## Abstract The basic method for synthesizing syndiotactic polystyrene‐__g__‐polybutadiene graft copolymers was investigated. First, the syndiotactic polystyrene copolymer, poly(styrene‐__co__‐4‐methylstyrene), was prepared by the copolymerization of styrene and 4‐methylstyrene monomer with a trich
## Abstract **Summary:** Three‐dimensionally ordered macroporous (3DOM) syndiotactic polystyrenes with pore size in the range of 71–286 nm were fabricated by means of silica templates using (dbm)~2~Ti(OPh)~2~/MAO catalytic system. The resulting materials were characterized by NMR, SEM, powder X‐ray
## Abstract Sulfonation of highly stereoregular syndiotactic polystyrene has been accomplished in 1,1,2‐trichloroethane and chloroform (60/40 v/v) mixed solvent. FTIR spectroscopy was used to confirm that the sulfonated syndiotactic polystyrene was the product of the sulfonation reactions. Sodium,
## Abstract **Summary:** Syndiotactic polystyrene (sPS)/organophilic clay nanocomposites were obtained by in situ coordination‐insertion polymerization of styrene. Two cationic surfactants (alkylammonium and alkylphosphonium) were used for the intercalation of montmorillonite (MMT). For each organi
