Provided are: an epoxy resin composition which enables the production of a carbon-fiber-reinforced composite material having excellent tensile strength and compressive strength and suitable as a material for structures; a prepreg; and a carbon-fiber-reinforced composite material. An epoxy resin composition characterized by comprising at least [A] an epoxy resin having a structure represented by formula (1), [B] an epoxy resin having at least one amine-type glycidyl group or at least one ether-type glycidyl group and having a liquid form at 40 C. and [C] a curing agent; and a prepreg and a carbon-fiber-reinforced composite material, each produced using the epoxy resin composition. ##STR00001##
(In the formula, R.sub.1 to R.sub.4 independently represent at least one atom or group selected from the group consisting of a hydrogen atom, an aliphatic hydrocarbon group having 1 to 4 carbon atoms, an alicyclic hydrocarbon group having 4 or less carbon atoms, and a halogen atom.)

Aspects described herein generally describe epoxy resins and methods of epoxy resin formation. In some embodiments, a resin includes the reaction product of one or more polythiols, one or more polyepoxides, one or more fillers and one or more amine catalysts. Polythiols have between two and about ten thiol moieties. Polyepoxides have between two and about ten epoxy moieties. One or more amine catalysts of the formula NR.sub.1R.sub.2R.sub.3, wherein each of R.sub.1, R.sub.2, and R.sub.3 is independently linear or branched C1-20 alkyl or two or more of R.sub.1, R.sub.2, and R.sub.3 combine to form cycloalkyl. The resin has a compressive strength of at least 14 ksi at 2% offset at 70 F. and at least 8 ksi at 2% offset at 190 F.

Amino sulfonic acid based polymers are reaction products of amino sulfonic acids, an amine, polyepoxide compounds and epihalohydrin. The polymers may be used as levelers in copper electroplating baths, to provide good throwing power. Such reaction products may plate copper or copper alloys with good surface properties and good physical reliability.
