Abstract: The article describes the synthesis of macrocyclic poly(α-methylstyrene) by the reaction of living bifunctional poly(α-methylstyrene) with the p-bis(chloromethyl)-benzene at very low concentration. The samples thus obtained are fractionated and the fractions are characterized by the methods of light scattering, osmotic pressure and viscosity.The ratios ([η]exp)/[η]linear) of the intrinsic viscosities in toluene of the two fractions of the lowest molecular weight of cyclic products to that of the linear polymer with the same molecular weight are found to be 0.684 and 0.707 respectively.
