The structural characteristics of the film-forming aids.
Classification of film forming aids
Film forming aids can be classified according to their position in the system, and the types are shown in Table 18-9.
Experience has shown that AB type film-forming aids are the most effective film-forming aids currently in use.
In fact, the surface of the latex particles adsorbs the emulsifier. Whether the AB type film-forming aid is between the emulsion polymer and the emulsifier, or is
interlaced with the emulsifier and adsorbed on the emulsion polymer, or other methods, has not been reported.
DP nB and Dowan olP Ph have higher solubility in water.
