Method of producing hot melt resin for prepreg.

摘要

A method of producing a hot melt resin for use in the production of a prepreg which comprises: preparing a mixture of a bis(2-oxazoline) compound, a polyepoxy compound and an aromatic polyamine copmpound wherein when the amount of the bis(2-oxazoline) compound is indicated as [P] moles, and when the amounts of the polyepoxy compound and the aromatic polyamine compound are indicated as [E] and [M], respectively, wherein [E] = (2/m) x moles of the polyepoxy compound and [M] = (2/n) x moles of the aromatic polyamine compound wherein m and n are the functionality per molecule of the polyepoxy compound and the aromatic polyamine compound, respectively, then [M]/[E] = 3-8, and [M] - [E] </= [P] </= 2 [M] - [E]; heating the mixture to a melt so that the polyepoxy compound and the aromatic polyamine compound react together; adding a curing catalyst to the melt; and cooling the melt to form a solid.
