Notes:
The stability against electrolytes for all-sulfate, all-carboxyl, and all-hydroxyl, polystyrene model latexes followed the order, sulfate 〉 carboxyl 〉 hydroxyl when determined from an IR light scattering technique. Two types of hydroxyl endgroups were identified by 13C-NMR (chemical shift correlations, and model compound comparisons), for the polystyrene model latexes. One type was due to termination of growing chain with an oligomer with a single monomer unit, and the other due to termination of growing chains. The surface hydroxyl groups of an all-hydroxyl latex were derivatized with hexafluoroacetone, and quantified using 19F-NMR techniques. Good agreement with the indirect conductometric titration values were obtained.
