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(CHCMe2Ph)(N-2,6-iPr(2)-Ph)(OOCH3(CF3)(2))(2)] or [Mo(CHCMe2Ph)(N,6-iPr(2)Ph)-(OC(CH3)(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.
