An epoxy composition comprising a fatty acid epoxy selected from:
- and an aromatic non-coplanar triepoxy.
A method of producing a cured epoxy, the method comprising mixing an epoxy composition comprising:
- a fatty acid epoxy selected from:
- a hyperbranched prepolymer having terminal groups comprising epoxide groups, hydroxyl groups, carboxyl groups, or a combination thereof;
- and
- an aromatic non-coplanar triepoxy,
- with a curing agent to produce a curing mixture, and
- polymerizing the curing mixture by maintaining the curing mixture at a temperature and time sufficient for polymerizing the epoxy composition, thereby producing a cured epoxy.
