Transient devices are those where the controlled, programmable disappearance of a device is needed because retrieval is not possible or a different form of disposal is desired. The devices include electronic components such as sensors, and delivery vehicles, such as rigid-wing gliders and parachutes. Low ceiling temperature polymers are of interest for construction of such devices because their depolymerization from the solid to liquid or vapor can be triggered at and occur at ambient conditions. Triggering can occur by a photo, chemical or thermal activation. The synthesis of stable, cyclic homopolymers and copolymers of o-phthalaldehyde will be described. The mechanism of polymerization, triggering conditions and incorporation of volatile components into the polymer will also be discussed.  <br/>
