The preparation of several novel mono- and dipropenyl and divinyl ethers derived from renewable starting materials is described using simple, straightforward synthetic methods. Utilizing real-time infrared spectroscopy, the reactivity of the monomers in photoinitiated cationic polymerization was studied employing diaryliodonium and triarylsulfonium salts as photoinitiators. The monomers were shown to undergo very rapid cationic photopolymerization.
