Abstract
Novel thermoset epoxy polymers using the bisglycidyl ethers of anhydrosugars, such as isosorbide, isomannide, and isoidide, are disclosed. The bisglycidyl ethers are useful as substitutes for bisphenol A in the manufacture of thermoset epoxy ethers. The anhydrosugars are derived from renewable sources and the bisglycidyl ethers are not xenoestrogenic and the thermoset curing agents are likewise derived form renewable resources.
Claims2
An epoxy derived from renewable resources, comprising:
- (a) a resin comprising glycidyl ethers of plant-derived anhydrosugars;
- and
- (b) a curing agent selected from the group consisting of bis(3-aminopropyl)ethers of isosorbide, isomannide, and isoidide;
- and bisamines derived by replacement of the hydroxyl groups in isosorbide, isomannide, or isoidide with amino groups for curing the resin.
1 more element
An epoxy, comprising:
- (a) a water-soluble resin comprising glycidyl ethers of plant-derived anhydrosugars;
- (b) a water-soluble curing agent for curing the resin selected from the group consisting of bis(3-aminopropyl)ethers of isosorbide, ismannide, and isoidide;
- and bisamines derived by replacement of the hydroxyl groups in isosorbide, isomannide, or isoidide with amino groups;
- and
- (c) wherein the epoxy is cured at room temperature.
