ABSTRACT:
Disclosed are a composition and a process for preparation thereof, which composition comprises a novel alicyclic compound and an epoxidized compound thereof represented respectively by formulae (I) and (II) ##STR1## wherein Y.sup.1 represents at least one of the structural groups ##STR2## Y.sup.2 represents at least one of the the structural groups ##STR3## R.sup.a and R.sup.b each represent hydrogen or a methyl group, m represents a natural number of from 1 to 7, and n represents a natural number of from 1 to 20.
The composition (II) is a multi-functional alicyclic epoxidized compound, which has a property of being high in epoxy group density in a molecule compared with alicyclic conventional epoxy resins, which can provide resins having wide range properties from being hard to being soft.
