Kinetics mechanism and application to polymer synthesis macromolecular symposia 1990 model copolymerization reactions. Young drive los angeles ca 90095 1569 usa. The alkene can be deprotonated at the vinyl carbon adjacent to the oxygen.

Furthermore an experimentally simple stereoselective synthesis of of vinyl ethers is delineated using the same catalyst system. Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. Its reaction with acrolein is the first step in the commercial synthesis of glutaraldehyde. Organic letters 2018 20 15 4507 4511.

They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers. Soc 2003 125 4978 4979. Vinyl ethers undergo homopolymerization via a cationic mechanism. It is prone to polymerization leading to formation of polyvinyl ethers.
