A novel graft‐like copolymer of syndiotactic polystyrene ( s PS) with polybutadiene (PB) was synthesized by polymerization of styrene in a toluene solution of PB using the cyclopentadiene titanium trichloride (CpTiCl 3 )/methylaluminoxane (MAO) catalytic system. The effect of PB on the crystallization behavior of the copolymer was investigated by differential scanning calorimetry and wide angle X‐ray diffraction. Hydrogenation of the s PS/PB copolymer with p ‐toluenesulfonyl hydrazide afforded a PE‐ like copolymer.
