Cross-linked networks, such as thermosetting and UV-curable polyurethanes, are utilized in numerous commercial applications due to the unique mechanical, thermal, and chemical resistive properties imparted by the formation of irreversible covalent bonds.  However, cross-linked networks are difficult to degrade unless harsh chemical or thermal treatments are employed, which often results in environmental and safety issues.  To address this issue, we developed novel silyl-containing polyurethane networks that possess degradable capabilities.  We aim to further explore this work by preparing new polyurethane networks via the use of trifunctionalized silyl triols in addition to incorporation of an ethanolamine linker using a similar synthetic scheme in our previously described work.  New reaction venues will be explored to improve efficiency of reactions for scaling up to larger quantities.  The properties of these networks will be assessed in analogous manner to that of the initial silyl diol networks with disassembly quantified through multiple techniques.<br/>
