Claim 15:
16. A method of aerobic depolymerization of fiber-reinforced polymer (FRP) composites, the method comprising:
providing a fiber-reinforced matrix for recycling that includes a monomer repeat unit having the following formula:, degrading FRP matrix with a matrix digest solution that includes one or more catalysts, and an oxygen source as a terminal oxidant to recover fibers at a first predetermined temperature, wherein the one or more catalysts include; MnCl2; and
removing the fibers from the matrix digest solution after the fiber-reinforced matrix has been solubilized; and
recovering a tetraacetate having formula 6, where OAc is acetate.
