ABSORBENT ARTICLE

An absorbent article may include a top sheet that is liquid-permeable, a back sheet that is liquid-impermeable, and an absorbent body situated between the top sheet and the back sheet in a thickness direction. At least one of the top sheet and the back sheet may include a synthetic resin sheet that includes a synthetic resin component and an oxidative decomposer comprising a mixture of a carboxylate and a rare earth compound. The synthetic resin sheet may contain the oxidative decomposer in a mass ratio such that a decomposition rate index (D.sub.i), as determined by formula (1), is 7.8 or less:


D.sub.i=B.sub.rS.sub.a (1)

where B.sub.r represents a mass ratio (g/g) of the oxidative decomposer with respect to the synthetic resin component, and S.sub.a represents a specific surface area (cm.sup.2/g) of the synthetic resin sheet.

AEROBIC DEPOLYMERIZATION OF FIBER-REINFORCED COMPOSITES
20190203013 · 2019-07-04 ·

A method of aerobic depolymerization of fiber-reinforced polymer (FRP) composites using sustainable reagents and conditions. A cured matrix is digested into soluble monomers and oligomers by catalytic aerobic oxidation. Carbon fibers are removed for re-use, then the remaining material is treated and valuable monomers are isolated. The isolated monomers can be converted back into resin precursors for re-use. The method solves the problem created because the typically irreversible cure reaction impedes recycling and re-use of FRP composites.
