Some calculations of intrinsic viscosity and molecular weight distribution for trifunctional, randomly branched polymers

Abstract Computations have been performed of the intrinsic viscosity of trifunctional, randomly branched whole polymers. Both the Thurmond‐Zimm and the Zimm‐Kilb treatments of the viscosity of branched polymers have been combined with the Beasley molecular weight distribution function. The Beasley distribution function has also been compared with a function derived by Flory for trifunctionally branched condensation polymers. The two functions are in good agreement at low extents of branching, but at higher branch contents the former function extends to significantly higher molecular weights.
