Abstract

A re-epoxidized polyfunctional epoxy resin composition comprising the reaction product of: (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: (i) an aliphatic or cycloaliphatic hydroxyl-containing material; (ii) an epihalohydrin, (iii) a basic-acting substance, in the presence of (iv) a non-Lewis acid catalyst; and (v) optionally, one or more solvents; (II) an epihalohydrin; (III) a basic acting substance; in the presence of (IV) a non-Lewis acid catalyst; and (V) optionally, one or more solvents. A curable epoxy resin composition of the re-epoxidized polyfunctional epoxy resin composition and a thermoset of the curable composition is also disclosed.

First claim

What is claimed is:

1. A re-epoxidized polyfunctional epoxy resin composition comprising the reaction product of:
(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 of more solvents.

2. 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.
