摘要:

AbstractLong‐column meniscus‐depletion sedimentation equilibrium has been used to determine M̄n, M̄wand M̄zfor the Na+and (CH3)4N+salts of a high molecular weight poly(styrene sulphonate). Consideration has been given to ways of avoiding the need for dialysis when dealing with polyelectrolyte sol
