✦ Synopsis

A novel graft-like copolymer of syndiotactic polystyrene (sPS) 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 sPS/PB copolymer with p-toluenesulfonyl hydrazide afforded a PE-like copolymer.
