Abstract
Official abstract text for this publication.
Isosorbide-derived epoxies and methods of making same are disclosed. Isosorbide and its isomers are attached to glycidyl ether to make crosslinkable epoxy resin monomers. Adding the hydrophobic functional group into the backbone of isosorbide epoxy or adjusting the amount and type of crosslinker is operable to modify the mechanical properties and water uptake ratio (from <1 wt % to >50 wt %) of the isosorbide-derived epoxies for different uses. High water uptake epoxies with controllable biodegradation rate are suitable for drug delivery systems or extracellular matrices for biomedical applications, while low water uptake epoxies with strong mechanical properties may be used for can coatings, bone cements and other industrial additives and adhesives.
First claim
Opening claim text (preview).
What is claimed is: 1. An isosorbide-derived epoxy resin composition comprising an isosorbide glycidyl ether and a curing agent wherein the isosorbide glycidyl ether is an isosorbide bis(glycidyl benzoate). 2. The composition of claim 1 wherein the isosorbide bis(glycidyl benzoate) is selected from the group consisting of isosorbide bis(4-glycidyl benzoate), isosorbide bis(3-glycidyl benzoate) and isosorbide bis(2-glycidyl benzoate). 3. The composition according to claim 1 wherein the curing agent is selected from the group consisting of a polyetheramine crosslinker, a polyamide resin crosslinker, an isophorone diamine crosslinker, and methyl-5-norbornene-2,3-dicarboxylic anhydride (NMA) with benzyl dimethyl amine (BDMA) as catalyst. 4. A compound selected from the group consisting of isosorbide bis(4-glycidyl benzoate), isosorbide bis(3-glycidyl benzoate) and isosorbide bis(2-glycidyl benzoate). 5. A method of making an isosorbide-derived epoxy resin composition comprising combining an isosorbide glycidyl ether with a curing agent wherein the isosorbide glycidyl ether is an isosorbide bis(glycidyl benzoate). 6. The method of claim 5 wherein the isosorbide bis(glycidyl benzoate) is selected from the group consisting of isosorbide bis(4-glycidyl benzoate), isosorbide bis(3-glycidyl benzoate) and isosorbide bis(2-glycidyl benzoate). 7. The method according to claim 5 wherein the curing agent is selected from the group consisting of a polyetheramine crosslinker, a polyamide resin crosslinker, an isophorone diamine crosslinker, and methyl-5-norbornene-2,3-dicarboxylic anhydride (NMA) with benzyl dimethyl amine (BDMA) as catalyst.
