Study of Factors Influencing Properties of Acrylic Emulsion

The effects of the proportion of emulsifier, the feeding mode of buffer agent, the glass transition temperature(Tg) on the properties of acrylic emulsion were studied. The results show that the stability of acrylic emulsion is increased by using more nonionic emulsifier and feeding the buffer agent before polymerization wholly. The required emulsion can be obtained in this way. The properties of acrylic emulsion are deeply affected by glass transition temperature and polymerizing technology and the lowest-filming temperature is decreased greatly by using the polymeric design of soft-shell and hard-core.
