Abstract
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° C. to about 150° C. and between about 35 wt. % and about 65 wt. % of a hydrophilic polyethylene glycol divinyl ether.
