A Cannon Ubbelohde dilution viscometer was utilized to determine accurate intrinsic viscosity values on a set of three narrow molecular weight distribution polystyrene samples. The Mark-Houwink parameters were determined to be K=0.0017 dl/g. The mean squared end-to-end distance of a 124,700g/mol sample was 306 Å ±2 Å, a 193,000 g/mol sample was 381
