  <abstract type="Summary">Silylated polyurethanes are often the prime components of many sealants and adhesives. However the main drawback accompanying these products is the high viscosity of prepolymers after their synthesis. It has been revealed that the main reason for the increased prepolymer viscosity is a high amount of hydrogen bonding between urea and urethane groups. This thesis summarizes the development of several strategies for overcoming a severe viscosity buildup by eliminating or reducing the amount of hydrogen bonding. A variety of coupling reagents were prepared by modification of aminoalkoxysilanes.&lt;eng&gt;</abstract>
  <abstract type="Summary">Silylierte Polyurethane sind wichtige Komponenten für Dichtmittel und Klebstoffe. Jedoch zeigt sich ein Nachteil bei der Synthese der Prepolymere, bedingt durch die hohe Viskosität der Produkte. Grund für die hohe Viskosität sind die Wasserstoffbrückenbindungen zwischen den Harnstoff- und Urethangruppen. Die Arbeit beschäftigt sich mit der Entwicklung mehrerer Strategien zur Verminderung der Viskosität durch die Reduzierung von Wasserstoffbrückenbindungen. Eine Variation verschiedener Silankupplungsverbindungen wurde für die Modifikation von gewöhnlichen Aminoalkoxysilanen erhalten.&lt;ger&gt;</abstract>
