Waterborne latexes are produced via emulsion polymerization, in which surfactants or emulsifiers are the key components to control latex properties. Much effort has been made to reduce the impact of surfactants on the performance of waterborne formulations. One of the promising approaches is to use polymerizable or reactive surfactants to prepare latex polymers.
This month’s Formulating with Mike columncontinues the focus on resins and discusses acrylic emulsion polymerization, in particular, surfactant design and how it affects the polymerization of a vinyl-acrylic emulsion.
This month’s Formulating with Mike column covers the life cycle assessment of alkyd emulsions and concludes the four-part series on alkyd emulsification.
Semibatch emulsion polymerizations are predominately run in “starve-fed” mode, but what does that really mean? In this edition of PCI’s Did You Know column, EPCEd discusses the reasons to run in starve-fed mode, and more.
This month’s Formulating with Mike column is the conclusion to a three-part series, and covers the emulsification process as well as test data of alkyd emulsions.
This article discusses how to control and quantify the amount of mixed polymer content as it can directly relate to the final morphology of the latex particles during polymerization.
