Abstract: Waterborne polymer is a colloid system. According to the basic concepts of colloidal science the waterborne polymer system, including the emulsion, microemulsion, nano-emulsion, latex, water dispersions, sol and gel, water soluble resin, water reducible resin, etc, were discussed in the paper. The typical characteristics of the different waterborne polymer systems were analyzed, and their similarities and difference were indicated. Considering the current practice in paint industry and the performance characteristics of waterborne polymers(such as the content of the soluble polar groups in the polymer, molecular weight of the polymer, the ratio of hydrophilic/ hydrophobic group, etc. ) the waterborne polymers and its types were discussed In this paper.

Key words: waterborne polymers, colloid, emulsion, latex, water soluble polymers, water reducible polymers
