Relationship Between Structure and Properties in Waterborne Polyurethane Dispersions, 1998 Nonwovens Conference Proceedings
This paper is concerned with the relationship between structure and properties of waterborne polyurethanes. As an introduction it will cover the differences between condensation and addition polymerizations. Basic reactions of isocyanates will be discussed, leading to illustrations of how polymethanes are synthesized. The major raw materials in waterborne polyurethane synthesis and how they affect the structure property relations will be illustrated. Properties such as particle size, morphology, mechanical properties and end use properties will be discussed. Emphasis will be placed on cross linking reactions and how they affect end use properties.
