A process is provided for preparing an acrylic copolymer latex having improved mechanical and shear stability comprising emulsion polymerizing at least one ethylenically unsaturated monomer having up to 23 carbons in the presence of, by weight based on the total monomer content, a) from about 0.05 percent to about 5.0 percent of a protective colloid with a molecular weight of less than 75,000, and b) from about 0.01 percent to about 1.5 percent of a least one water soluble free radical polymerization initiator. This latex provides coating manufacturers the flexibility of either eliminating surfactants altogether from coating or to use small amounts thereof.
