PARTIALLY AND NUCLEARLY HYDROGENATED POLYFUNCTIONAL AROMATIC EPOXY RESIN AND EPOXY RESIN COMPOSITION CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain the subject resin having film suitability and useful for hot-melt adhesives, etc., by partially and nuclearly hydrogenating an aromatic epoxy compound having plural epoxy groups different in reactivity in the same molecule. SOLUTION: This resin has a structure in which 20-80% of aromatic nuclei of an aromatic epoxy compound having >=3 aromatic nuclei on the average and >=2 epoxy groups on the average in the molecule are hydrogenated and converted into an aliphatic ring structure. Furthermore, the objective resin is preferably obtained by using hydrogen in an amount of 20-80% based on the theoretical amount for hydrogenating reaction when hydrogenating all the aromatic nuclei of (A) the aromatic epoxy compound having the >=3 aromatic nuclei on the average and the >=2 epoxy groups on the average in the molecule in the presence of (B) a metal catalyst or epoxidizing an aromatic hydroxy compound having >=3 aromatic nuclei on the average and >=2 hydroxyl groups on the average in the molecule with epichlorohydrin.
