ABSTRACT:
The stability and physical properties of high molecular weight emulsion polymers are improved by the addition of a low molecular weight support resin during the emulsion polymerization process. The resin is soluble or dispersible in water or alkali and has a number average molecular weight between 500 and 20,000.
