Melt rheology of tadpole-shaped polystyrenes with different ring sizes

Linear melt rheology of a single-tail tadpole-shaped polystyrene, ST-30/80, having ring and linear sizes ofM_R∼ 30 kg mol⁻¹andM_L∼ 80 kg mol⁻¹, respectively, was examined, and the effect of ring size on the rheological properties was discussed.
