Abstract We prepared new varied diblock copolymers by ring‐opening metathesis polymerization of functionalized norbornenes and cyclooctene in the presence of Schrock‐type initiators, either [Mo(CHCMe 2 Ph)(N‐2,6‐ i Pr 2 Ph)(OCCH 3 (CF 3 ) 2 ) 2 ] or [Mo(CHCMe 2 Ph)(N‐2,6‐ i Pr 2 Ph)(OC(CH 3 ) 3 ) 2 ]. The block copolymers were microphase separated and presented the individual phases of each polymer block constituent, that were amorphous/amorphous, amorphous/semicrystalline, or semicrystalline/liquid‐crystalline. One example of such a block copolymer is shown.
