Abstract
General purpose inherently tacky acrylic pressure sensitive adhesive polymers formed of alkyl acrylates, vinyl esters, and saturated carboxylic acids, having improved properties, a lower residual monomer content are formed by a sequential emulsion polymerization process in which 40 to 70 percent, typically 45 percent, of the monomers are incrementally added to a reactor as a first charge containing substantially all of the vinyl esters, the balance of the monomers being fed in a second incremental charge.
