Abstract:
The present disclosure provides a composition of matter comprising purified cyclic poly(phthalaldehyde) (cPPA) and a plasticizer. The composition enables thermal processing and molding in bulk quantities, and is designed to degrade when contacted by an acid or exposed to a high enough temperature. Photodegradable cPPA containing a photooxidant is disclosed. Methods of making and recycling the composition of matter are also provided.
