Herein, spindle‐shaped block copolymer (BCP) nanoparticles are used in seeded polymerization of methyl methacrylate as a novel approach to generating cylindrical nanostructures. The chain‐extension of BCP seeds by an amorphous coil‐type polymer within the seed core composed of semifluorinated liquid‐crystalline blocks triggers the deforming, stretching, and directional growth of the seeds along the long axis, eventually leads to nanorods.
