The Schulz and Blaschke equation in the rearranged form of Hart was used for reasonably precise calculation of the intrinsic viscosity from a single measured specific viscosity for stereoregular polybutene‐1 in Decalin and for a series of alkyl methacrylate polymers in good and poor solvents. A single value of N can be used for each system provided careful measurements are made at specific viscosities somewhat below 1.
