Epoxy resin compositions

A process for preparing a re-epoxidized polyfunctional epoxy resin composition comprising reacting:

• (I) an epoxidized polyfunctional epoxy resin oligomeric composition comprising a polyfunctional aliphatic or cycloaliphatic epoxy resin which has been isolated from an epoxy resin product formed as a result of an epoxidation process comprising the reaction of:
• (A) a material selected from the group consisting of cis-, trans-1,3- and
• 1,4-cyclohexanedimethanol;
• cis-, trans-1,2-cyclohexanedimethanol;
• cis-, trans-1,3-cyclohexanedimethanol;
• cis-, trans-1,4-cyclohexanedimethanol;
• 4-methyl-1,2-cyclohexanedimethanol;
• 4-methyl-1,1-cyclohexanedimethanol;
• 1,1-cyclohexanedimethanol;
• a cyclohexenedimethanol including 3-cyclohexene-1,1-dimethanol;
• 3-cyclohexene-1,1-dimethanol, 6-methyl-;
• 4,6-dimethyl-3-cyclohexene-1,1-dimethanol;
• cyclohex-2-ene-1,1-dimethanol;
• 1,1-cyclohexanediethanol;
• 1,4-bis(2-hydroxyethoxy)cyclohexane;
• 1,4-cyclohexanediethanol;
• and 1,4-bis(2-hydroxyethyloxy)cyclohex-2-ene;
• (B) an epihalohydrin,
• (C) a basic-acting substance,
• (D) a non-Lewis acid catalyst;
• and
• (E) optionally, one or more solvents;
• (II) an epihalohydrin;
• (III) a basic acting substance;
• (IV) a non-Lewis acid catalyst;
• and;
• (V) optionally, one or more solvents.
