This invention relates to a process for preparing polymers which contain as polymerized units hydrophobic monomers wherein a stable emulsion is formed and the formation of suspension particles is minimized. The process includes making a concentrated monomer emulsion, diluting the concentrated monomer emulsion with water, feeding the diluted monomer emulsion to a reactor, and polymerizing the monomer.
