| Abstract: | The stability of emulsifier‐minor emulsion polymerization and the final latices depends on whether water‐soluble monomers can be bound to the particle after polymerization, which relies on the hydrophilicity of the water‐soluble monomers. Less hydrophilic monomers are apt to be buried in the latex particle, but extremely hydrophilic monomers tend to homopolymerize in the water phase. The suitable hydrophilic index I/O of water‐soluble monomers is preferably 3–5. The adhesion power and water resistance of emulsifier‐minor latex films are better than that of conventional latex film, but the impact resistance and gloss of the former are poorer. The gloss and water resistance of the emulsifier‐minor latex films are relevant to the type of water‐soluble monomers. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 99: 796–801, 2006 |
