ABSTRACT:
Acrylic resin dispersions are prepared by a monomer addition process in the presence of a free-radical initiator and an emulsifier, wherein a portion of the emulsifier is dissolved in the initial aqueous phase and the remaining portion in the added monomer phase. The new process decreases the formation of coagulates, reduces the required amount of emulsifier, and allows the preparation of dispersions of resins incorporating a large proportion of units derived from water-soluble monomers, such as carboxylic acids.
