Preparation of Poly(Alkyl Vinyl Ethers) for Nonlinear Optical Applications 2/Synthesis and Cationic Polymerization of 4'-(2-vinyloxyethoxy)-4-nitrostilbene
4'-(2-vinyloxyethoxy)-4-nitrostilbene was prepared by the reaction of 4'-hydroxy-4-nitrostilbene with 2-iodoethyl vinyl ether. the monomer was polymerized with cationic initiators to obtain a poly(ethyl vinyl ether) with 4'-oxy-4-nitrostilbene as a NLO-phore in the side chain. The resulting polymer was soluble in common solvents such as chloroform and DMSO. The inherent viscosities of polymer were in the range of 0.25-0.30 dL/g in chloroform. The polymer showed a good thermal stability in TGA thermogram. Solution-casted films were cloudy and brittle with a Tg of 63℃.
