can be carried out in either bulk or solution polymerization in the solution polymerization process aromatic hydrocarbons and chlorinated hydrocarbons having boiling points of 50 u00b0 to 150 u00b0 c such as e g methylene chloride carbon tetrachloride toluene benzene or nitrobenzene can suitably be used the solvent can be used in an amount of 0 1 to 90 preferably 1 to 50 by weight of the vinyl ether or epoxy compound containing the furanacrylate group where the polymerization is effected in solution the concentration of the monomer or monomers is suitably from about 1 to 80 by weight the polymerization temperature is generally within the range of from about 100 u00b0 to 150 u00b0 c where monomer represented by the general formula i 39 is used it is particularly preferable to conduct the polymerization at 78 u00b0 to 0 u00b0 c while where monomer represented by the general formula ii 39 is used it is particularly preferable to effect the polymerization at 78 u00b0 to 80 u00b0 c details of the polymerization procedure are described by higashimura et al in kobunshi kagaku high molecular chemistry i vol 16 of kindai kogyo kaku recent industrial chemistry series published by asakura shoten in 1967.
