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.
