Abstract
Diglycidyl ethers are prepared from a mixture of isomers of 1,1-bis(hydroxyphenyl)heptane. The diglycidyl ethers have low viscosity and good compatibility with aliphatic hydrocarbon solvents; they can be cured with the usual curing agents for epoxy resins, e.g., polyamines, and can be used in solventless coating compositions.
