| 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, and1-35% 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, and2-95% by weight of:unsaturated oligomers, andsaid 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. |
