Microgels, intramolecularly crosslinked macromolecules with sizes of less than 100 nm, were originally manufactured via an emulsion polymerization process involving the use of novel amphiphilic oligomers containing the zwitterion moiety as emulsifiers. Application of microgels as additives to coatings has been studied here. Newtonian flow of an original coating composition was altered to pseudoplastic flow by the addition of microgels. The mechanism of this fluidity alteration was discussed in terms of electron microscopic observation of the coating composition.
