Abstract
Abstract Novel polyglycidylethers are prepared from a mixture of isomers of 1,1-bis(hydroxyphenyl)heptane. The polyglycidyl ethers have a good compatibility with aliphatic hydrocarbon solvents, can be cured with the usual curing agents, and can be used as base materials for the preparation of anionic or cationic aqueous thermosetting paint binders. The polyglycidyl ethers of low molecular weight have a low viscosity.
