Poly( N ‐ n ‐butylitaconimide) was prepared by radical polymerization in benzene and in bulk at 60°C and was subsequently fractionated at 30°C with benzene and methanol as solvent and nonsolvent, respectively. Relationships between molecular weight and intrinsic viscosity (Mark‐Houwink‐Sakurada equations) in tetrahydrofuran, benzene, and toluene at 30°C are established. From the Burchard‐Stockmayer‐Fixman plot, the characteristic ratio of this polymer is determined, and local chain conformation is discussed in relation to the termination process in radical polymerization.
