## Abstract

The invention relates to a blend of divinyl ethers and their use as diluents for irradiation curable resins, which blend comprises between about 65 wt. % and about 35 wt. % of a hydrophobic divinyl ether containing from 6 to 30 carbon atoms and having a Tg of from about 20.degree. C. to about 150.degree. C. and between about 35 wt. % and about 65 wt. % of a hydrophilic polyethylene glycol divinyl ether.

## Claims

C. and (b) between about 35 wt. % and about 65 wt. % of a hydrophilic polyethylene glycol divinyl ether which blend is mixed with between about 10 wt. % and about 70 wt. %, based on total composition, of an irradiation curable epoxy resin having a molecular weight of from about 300 to about 5,000.

### Claim 2 (depends on 1)
