Recyclable and reworkable epoxy resins

An epoxy resin component for a recyclable epoxy resin system, the epoxy resin component having a structural Formula I:

• wherein m=0, 1, or 2 such that
• when m=0 then n=4;
• when m=1 then n=3;
• or
• when if m=2 then n=2;
• R1 is selected from hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, cycloalkynyl, aryl, heterocyclic, heterocycloalkyl, heterocycloalkenyl, heteroaryl, alkoxyaryl, alkoxy alkyl;
• D is selected from oxygen and
• and
• B is selected from arylene, alkylene-arylene, arylene-alkylene-arylene, and alkylene-cycloalkylene,
• with the proviso that:
• when m=0 and D is oxygen, B is selected from alkylene-arylene, alkylene-cycloalkylene, and arylene-alkylene-arylene;
• when m=0 and D is
• B is selected from arylene, alkylene-arylene, and alkylene-cycloalkylene;
• when m=1 and D is oxygen, B is selected from alkylene-arylene, alkylene-cycloalkylene, and arylene-alkylene-arylene;
• when m=1 and D is
• B is selected from arylene and alkylene-arylene;
• when m=2 and D is oxygen, B is alkylene-cycloalkylene;
• and
• when m=2 and D is
• B is selected from arylene, alkylene-arylene, and alkylene-cycloalkylene.
