Abstract Fibers having structures comprising　alternating liquid crystal (LC)/amorphous layers were stretched in the layer normal direction and the microdomain structure and stress were simultaneously measured for LC block copolymers having different molecular weights and amorphous segments. The LC block copolymers comprise of main-chain type LC polyester forming a smectic LC and segregating from the amorphous blocks of poly(ethyl methacrylate) or poly(methyl methacrylate) bonded to both the ends. These copolymers, forming highly ordered, near-single-crystal lamellar microdomains lying the normal in the fiber axis direction, were used to examine the effects of the molecular weight and the amorphous segments with different Tg.
