A procedure is described for computing sedimentation coefficient distributions from the time derivative of the sedimentation velocity concentration profile. Use of the time derivative, (delta c/delta t)r, instead of the radial derivative, (delta c/delta r)t, is desirable because it is independent of
Abstraet--A study has been made of the concentration dependence of the sedimentation coefficient S of the two 0 systems (I) polymethylmcthacrylate in n-butyl chloride at 35 Β° and (II) polystyrene in cyclohexane at 34Β°; also for the non-0 system CIII) polyisobuty[ene in cyclohexane at 34 Β°.
