Abstract
The intrinsic viscosity and the sedimentation constant of randomly branched polydisperse polymers were calculated using a molecular-weight distribution function derived by Stockmayer and incorporating this function into the theories of intrinsic viscosity and friction constant of a branched molecule. Randomly branched polydisperse polymers were prepared by copolymerization of methyl methacrylate with ethylene dimethacrylate and the hydrodynamic properties were determined by experiment and compared with the theories. It was found that the intrinsic viscosity of randomly branched polymers was well characterized by Zimm and Kilb’s g1/2-rule, at least in the theta state.
