The intrinsic viscosity–molecular weight relationship has been determined for synthetic cis ‐1,4‐polyisoprene prepared with butyllithium initiator. The best representation of our results is the equation, [η] = 2.00 × 10 −4 ( M̄ v ) 0.728 , for intrinsic viscosities determined in toluene at 30°C. This relationship agrees, within experimental error, with that obtained for natural rubber by Carter, Scott, and Magat.
