Epoxy-anhydride　resins　are　widely　used　in　engineering　fields　due　to　their　excellent　performance.　However,　the　insolubility　and　infusibility　make　the　recycling　of　epoxy　resins　challenging.　The　development　of　degradable　epoxy　resins　with　stable　covalent　networks　provides　an　efficient　solution　to　the　recycling　of　thermosets.　In　this　paper,　2,4,6-tris(dimethylaminomethyl)phenol　(DMP-30)　is　incorporated　into　the　epoxy-glutaric　anhydride　(GA)　system　to　prepare　high-performance　epoxy　resins　that　can　be　recycled　below　200C　at　ordinary　pressure　via　ethylene　glycol　(EG)　participated　transesterification.　The　tertiary　amine　groups　in　DMP-30　can　catalyze　the　curing　reaction　of　epoxy　and　anhydride,　as　well　as　the　transesterification　between　ester　bonds　and　alcoholic　hydroxyl　groups.　Compared　with　early　recyclable　anhydride-cured　epoxy　resins,　the　preparation　and　recycling　of　diglycidyl　ether　of　bisphenol　A　(DGEBA)/GA/DMP-30　systems　do　not　need　any　special　catalysts　such　as　TBD,　Zn(Ac)2,　etc.,　which　are　usually　expensive,　toxic,　and　have　poor　compatibility　with　other　compounds.　The　resulting　resins　have　glass　transition　temperatures　and　strengths　similar　to　those　of　conventional　epoxy　resins.　The　influences　of　GA　content,　DMP-30　content,　and　temperature　on　the　dissolution　rate　were　studied.　The　decomposed　epoxy　oligomer　(DEO)　is　further　used　as　a　reaction　ingredient　to　prepare　new　resins.　It　is　found　that　the　DEO　can　improve　the　toughness　of　epoxy　resins　significantly.　This　work　provides　a　simple　method　to　prepare　readily　recyclable　epoxy　resins,　which　is　of　low-cost　and　easy　to　implement.　©　2021　by　the　authors.　Licensee　MDPI,　Basel,　Switzerland.
