Phenolische Verbindungen sowie ihre Glycidylether

摘要

The present invention relates to a phenolic compound of formula I: and to an epoxy resin of the formula II: In the above formulae I and II Ar is an aromatic moiety, L is a divalent hexanenorbornane linking moiety, L' is a divalent cycloaliphatic moiety, Gly is a glycidyl ether group, and each of m and n is a number within the range of 0 to 10. The above phenols include the product of addition reaction of phenol with a cyclohexenenorbornene compound such as 5-(3-cyclohexen-1-yl)bicyclo[2.2.1]hept-2-ene and the above epoxy resins include the glycidation product thereof. Epoxy resin compositions comprising either the above phenolic compound or the above epoxy resin have in particular low melt viscosity are useful as resinous component of high-performance electrical laminating and encapsulation formulations.
