Embodiments of the present disclosure are directed to heterogeneous advanced epoxy resins formed by reacting a mononuclear aromatic diglycidyl ether and a diphenol, more specifically, embodiments of the present disclosure are directed to heterogeneous advanced epoxy resins formed by reacting the mononuclear aromatic diglycidyl ether and the diphenol in a molar ratio of the mononuclear aromatic diglycidyl ether to the diphenol in a range from 1.5 to 1.0 to 5.0 to 1.0.
First claim
Opening claim text (preview).
What is claimed: 1 . A heterogeneous advanced epoxy resin formed by reacting a mononuclear aromatic diglycidyl ether and a diphenol in a molar ratio of the mononuclear aromatic diglycidyl ether to the diphenol in a range from 1.5 to 1.0 to 5.0 to 1.0, wherein the mononuclear aromatic diglycidyl ether is selected from the group consisting of an alkyl hydroquinone diglycidyl ether, an alkyl resorcinol diglycidyl ether, an alkyl catechol diglycidyl ether, and combinations thereof 2 . The heterogeneous advanced epoxy resin of claim 1 , wherein the mononuclear aromatic diglycidyl ether is selected from the group consisting of 4-hexyl resorcinol diglycidyl ether, 5-pentyl resorcinol diglycidyl ether, 4-ethyl resorcinol diglycidyl ether, tert-butyl resorcinol diglycidyl ether, 2-n-propyl resorcinol diglycidyl ether, 4-(2-octyl) resorcinol diglycidyl ether, and 4-styryl resorcinol diglycidyl ether. 3 . The heterogeneous advanced epoxy resin of claim 1 , wherein the diphenol is selected from the group consisting of an alkyl hydroquinone, an alkyl resorcinol, an alkyl catechol, and combinations thereof. 4 . The heterogeneous advanced epoxy resin of claim 3 , wherein the diphenol is selected from the group consisting of 4-ethyl resorcinol, 4-hexyl resorcinol, 2-n-propyl resorcinol, and tert-butyl hydroquinone. 5 . The heterogeneous advanced epoxy resin of claim 3 , wherein an alkyl group of the diphenol is a substituted or unsubstituted alkyl having 2 to 18 carbons. 6 . The heterogeneous advanced epoxy resin of claim 1 , wherein an alkyl group of the mononuclear aromatic diglycidyl ether is a substituted or unsubstituted alkyl group having 2 to 18 carbons. 7 . The heterogeneous advanced epoxy resin of claim 1 , wherein the mononuclear aromatic diglycidyl ether and the diphenol are reacted at a temperature in a range from 135 degrees Celsius (° C.) to 250° C. 8 . The heterogeneous advanced epoxy resin of claim 1 , wherein the molar ratio of the mononuclear aromatic diglycidyl ether to the diphenol is 2.5 to 1.0. 9 . The heterogeneous advanced epoxy resin of claim 1 , wherein the heterogeneous advanced epoxy resin has an epoxide equivalent weight (EEW) in a range from 180 to 750 grams/equivalent (g/eq). 10 . The heterogeneous advanced epoxy resin of claim 1 , wherein the EEW is in a range from 200 to 500 g/eq. 11 . The heterogeneous advanced epoxy resin of claim 1 , wherein the heterogeneous advanced epoxy resin is a flowable liquid at 25° C. 12 . The heterogeneous advanced epoxy resin of claim 11 , wherein the viscosity of the heterogeneous advanced epoxy resin is less than 100,000 centipoise at 25° C.
