The unperturbed dimensions of isotactic, optically active poly-(S)-4-methyl-1-hexene and isotactic poly-4-methyl-1-pentene were estimated from viscosity data. The characteristic ratio h02/nl2 for the optically active polymer is remarkably higher than that of the structurally analogous poly-4-methyl-1-pentene. The results support, at least qualitatively, the previously outlined model for the conformation of isotactic, optically active poly-α-olefin chains in solution.
