Cross-linked networks, such as thermosetting 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. Previously prepared thermosetting networks from the Naval Research Laboratory have shown the ability to disassemble and release small molecules.  To optimize the properties of the previously prepared thermosets, we synthesized new analogues of the silyl based diols and triols that extend the chain even further, while utilizing a new synthetic scheme to increase overall yield.<br/>
