Abstract
Hydrodynamic behavior of P alpha MS in the subtheta regime was examined to evaluate behavior of transport properties ( eta ) and D sub z and their associated interrelationships. The subtheta collapse of P alpha MS was also compared with polystyrene. The chemical structure of the chain influenced the collapse transition, implying that ternary interactions are different for chemically-dissimilar chains. Graphs. 14 ref.--D.M.Y.
