    Abstract: The norbornene derivative of the present invention is represented by the following formula (Im). According to the present invention, a novel norbornene derivative that is useful as a precursor monomer for preparing a cycloolefin polymer exhibiting excellent transparency, heat resistance and low-water absorption properties and having been freely controlled in the birefringence properties and the wavelength dispersion properties can be provided. According to the present invention, further, a norbornene ring-opened (co)polymer having excellent transparency and heat resistance, exhibiting high solubility in organic solvents and having specific birefringence properties and wavelength dependence, and a process for preparing the ring-opened (co)polymer can be provided.

    Abstract: A polymerizable vinylester composition is described which comprises at least three monomers and oligomers, said composition comprising: 2-95% by weight of: diaryl compounds comprising at least two aryl groups linked directly together or bridged by a linking group, each of said at least two aryl groups having a vinyl group attached thereto, 2-65% by weight of: a methacrylic acid ester of a vinyl-substituted sec-ethylol-diaryl oxide or its thioether or methine or biphenyl counterpart, and 1-35% by weight of: dimethacrylic acid esters of bis-[4-(1-hydroxyethyl)aryl] ether, thioether or methine, or their counterparts where aromatic rings are linked together directly, and 2-95% by weight of: unsaturated oligomers, and said reactive composition has less than 1% mol basis of monoaryl phenolic compounds. A method of synthesizing polymerizable divinylaromatic compositions of the invention is described comprising the steps of dehydrating a diol by heating wherein heating said diols is performed in the presence of a sulfonic acid at a concentration of 0.5-10.0 mmole/L in aromatic solvent at the boiling temperature of the reaction mixture in the range of 100-160° C., and then removing at least some water produced by the dehydration reaction.
