摘要： This invention is based upon the unexpected discovery that styrene-butadiene block copolymers having syndiotactic polystyrene (sPS) blocks and cis-1,4-polybutadiene (PBd) blocks can be synthesized by polymerizing styrene and 1,3-butadiene utilizing certain catalyst systems when the polymerization is conducted at a pressure which is within the range of about 10 mm of mercury to about 50 mm of mercury at a temperature which is within the range of about 0° C. to about 100° C. This invention more specifically discloses a styrene-butadiene block copolymer which is comprised of (a) syndiotactic polystyrene blocks and (b) cis-1,4-polybutadiene blocks, wherein said cis-1,4-polybutadiene blocks have a vinyl content of up to about 20 percent, wherein the syndiotactic polystyrene blocks have a syndiotactic microstructure content of at least 50 percent, wherein the block copolymer contains at least five syndiotactic polystyrene blocks and wherein said block copolymer has a number average molecular weight which is within the range of about 10,000 to about 700,000.
