(A) Chimeric polymers from ring and linear chains fused together. (B) Tadpole-shaped polymers are the simplest such chimeric structure, shown as a schematic with orange “head” and gray “tail.” (C) Typical simulated conformation of a tadpole and (D) an equilibrated system of 80 tadpoles. Here the circular and linear sections both have 250 monomers, written (C, L) = (250, 250).
