Recalculation of Some Reactivity Ratios

Abstract In attempting to improve the evaluation of Q and e values, some 900 reactivity ratios were recalculated.

An Expanded Listing of Revised Q and e Values

Abstract Recalculation of reactivity ratios has led to improved Q and e values for a variety of monomers.

Determination of Q and e Values by a Least Squares Technique

Abstract A more precise determination of Q and e values for vinyl monomers can be attained through the use of a linear least squares technique.

Q and e Values of Telogens

Abstract By using a linear least-squares technique, the Q and e values of a number of telogens have been determined.

Surface Tensions of Proteins in Aqueous Solutions

Changes in conformation of proteins in solution may be detected by determin ing the relative surface tensions of their solutions. Of the proteins examined, all of the enzymes had distinct changes in surface tensions upon going from a 3M NaCl medium to a salt-free aqueous solution. Only two of the seven non- enzymic proteins underwent detectable changes in the same cycle. These relative surface tensions could be of value in determining adsorption/elution profiles for hydrophobic interaction chromatography.
