US 11,859,077 B2 · Solvent-less ionic liquid epoxy resin

Abstract

Solvent free epoxy system that includes: a hardener compound H comprising: a molecular structure (Y1—R1—Y2), wherein R1 is an ionic moiety Y1 is a nucleophilic group and Y2 nucleophilic group; and an ionic moiety A acting as a counter ion to R1; and an epoxy compound E comprising: a molecular structure (Z1—R2—Z2), wherein R2 is an ionic moiety, Z1 comprises an epoxide group, and Z2 comprises an epoxide group; and an ionic moiety B acting as a counter ion to R2. In embodiments, the epoxy compound E and/or the hardener H is comprised in a solvent-less ionic liquid. The systems can further include accelerators, crosslinkers, plasticizers, inhibitors, ionic hydrophobic and/or super-hydrophobic compounds, ionic hydrophilic compounds, ionic transitional hydrophobic/hydrophilic compounds, biological active compounds, and/or plasticizer compounds. Polymers made from the disclosed epoxy systems and their methods of used.

A method of preparing a diamine imidazolium halide, the method comprising:

reacting a haloalkylamine with a triphenylmethyl halide to yield a protected haloalkylamine, wherein the haloalkylamine is a primary amine and the protected haloalkylamine is a secondary amine;
reacting the protected haloalkylamine with an alkylimidazole to yield a bisubstituted alkylimidazole;
removing the triphenylmethyl from the bisubstituted alkylimidazole to yield a halide derivative of the bisubstituted alkylimidazole;
and
neutralizing the halide derivative of the bisubstituted alkylimidazole to yield the diamine imidazolium halide,
wherein:
the haloalkylamine is bromoethylamine,
the triphenylmethyl halide is tritylchloride,
the protected haloalkylamine is bromoethyltriphenylmethylamine;
the alkylimidazole is 2-methylimidazole, and
