Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. The alkene portion of the molecule is reactive in many ways. Use of ethyl vinyl ether in the synthesis of glutaraldehyde. They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers.
