Structure of 2,2'-bis(4-cyanatophenyl)isopropylidene

The title compound is monoclinic: a = 13.345(3), b = 11.393(2), c = 10.046(5) Angstroem, β = 108.48(2) deg, Z = 4, P21/c.The structure was determined by direct methods, using MoKα diffractometer data, and refined by full-matrix least squares to R = 0.045 for 1463 reflections.The structure shows a central tetrahedral carbon atom surrounded by two methyl and two phenylcyanate groups.The geometry of the cyanate group compares well with that in 4-chloro-3,5-dimethylphenyl cyanate, the only example of an organic cyanate in the Cambridge Crystallographic data-base (V.3).The intermolecular nitrile, C-H, distances were examined for evidence of a possible dimerization interaction; no significant distances were found.

METHOD FOR PRODUCING CYANOGEN-HALIDE, CYANATE ESTER COMPOUND AND METHOD FOR PRODUCING THE SAME, AND RESIN COMPOSITION

A method for efficiently producing a cyanogen halide with suppressed side effects, and a method for producing a high-purity cyanate ester compound at a high yield includes contacting a halogen molecule with an aqueous solution containing hydrogen cyanide and/or a metal cyanide, so that the hydrogen cyanide and/or the metal cyanide is allowed to react with the halogen molecule in the reaction solution to obtain the cyanogen halide, wherein more than 1 mole of the hydrogen cyanide or the metal cyanide is used based on 1 mole of the halogen molecule, and when an amount of substance of an unreacted hydrogen cyanide or an unreacted metal cyanide is defined as mole (A) and an amount of substance of the generated cyanogen halide is defined as mole (B), the reaction is terminated in a state in which (A):(A)+(B) is between 0.00009:1 and 0.2:1.

Mesogenic polycyanates and thermosets thereof

Novel polycyanate and polycyanamide compositions containing one or more mesogenic or rodlike moieties, when cured, result in products having improved properties.
