Polymers in Adhesives

The polymer particle size in latexes is far too small to he effective for adhesive applications. Therefore, many of these very tiny budding Uocks must coalesce through the diffusion adhesion mechanism to provide an optimum sized critical mass of polymer for the particular adhesive requirement. Methods of bringing the CTUcial number of particles together at the proper point of intersection for optimum bonding represents much of the ingenuity and skill involved in the utilization of emulsion polymers in adhesive applications. 

The rectangular region shoiild be cross-cut along the coordinate lines. Within the limits of the allowable ratios of the element sides, the coordinate lines can be arbitrarily thickened, but narrow elements must be placed right after the broad ones. These two conditions are important when studying the stress-state of thin interlayers for example, polymers in adhesive-bonded joints.
