Preface

Aqueous polymer dispersions are important raw materials used in a variety of in-dustrial processes. They consist of very small polymer particles dispersed in water and appear as milky fluids. When finally processed and providing the function for which they were selected, they are barely visible. Polymer dispersions are used to protect metal, wood, and leather against water and microorganisms, and are used as binders for pigments, fillers, and fibers and to finish the surfaces of metal, wood or paper. Protecting, binding, and finishing are the essential effects achieved by use of polymer dispersions.

In most applications the water will be evaporated and a functional polymer re-mains. This can be hard or tacky, plastic or elastic, transparent or opaque. Accord-ingly, they are used for coatings or as adhesives, for binders or foams, for clear coat varnishes or opacifiers. It is even possible to reconcile these classically contradictory properties by proper design of a single dispersion or by mixing several.

Even small amounts of polymer dispersion are able to improve considerably the properties of different binders, e.g. starch, bitumen, or cement.

The huge variety of applications continues into the area of solid plastic materials – impact modifiers are added to improve the properties of plastic materials. Dipping goods, e.g. gloves, and latex foams for mattresses are polymeric materials which are made directly from polymer dispersions.

Finally, there are also applications in which polymer dispersions remain in their liquid form – they are used as drug carriers, in medical diagnosis, and in liquid soap. This book focuses on the applications of aqueous polymer dispersions. The chap-ters on synthesis and characterization should be regarded as an introduction and should aid understanding of the applications. The applications of aqueous polymer dispersions have developed differently, both historically and regionally. Regulatory issues have contributed to these differences. The strongest development of polymer dispersions occurred in Europe and North America in the middle of the 20th centu-ry. The differences between these two regions are emphasized.

We are specially grateful to all the authors who helped us make this global com-parison and acknowledge the authors’ companies, for approving and supporting this work.
