A new rare earth catalyst system was found in our laboratory. Not only styrene and iso-prene are copolymerized but also styrene and butadiene are copolymerized with the new catalyst system-4f metal compounds-alkyl aluminium compounds-other components. The copolymers are characterized as the block copolymers containing 4.0-4.5(%) gels
22.0-97.7(%) cis-l
4-contents and 8.3-79.8 (mol%) styrene contents by means of IR
