ABSTRACT:
Photopolymerizable epoxide compositions are provided which contain photoinitiators decomposable upon exposure to electromagnetic radiation to produce a Lewis acid and polymerizable epoxide compounds including an epoxide ether compound having the following general structural formula: ##STR1## wherein n equals 1-3 and wherein R is an aliphatic or cycloaliphatic group having 5-12 carbon atoms. Other epoxide compounds may be used in combination therewith to provide compositions which cure rapidly to a tack-free condition at ambient temperatures. Specific epoxide ethers disclosed are those in which n=1 and R is a group selected from the class of 2,2-dimethylpropane, 2-ethyl-1,3-hexane, 1,4-dimethylcyclohexane and 1,10-decane.
