ref Chemistry and Technology of Cyanate Ester Resins, Ian Hamerton Ed. Blackie Academic and Professional Glasgow, 1994 ref Unreferenced date October 2010 Cyanate esters are chemical substance s generally based on a bisphenol or novolac derivative, in which the hydrogen atom of the phenolic OH group is substituted by a cyanide group. The resulting product with an OCN group is named a cyanate ester . Cyanate esters can be Curing chemistry cured and postcured by heating, either alone at elevated temperatures or at lower temperatures in presence of a suitable catalyst. The most common catalysts are transition metal complexes of cobalt, copper, manganese and zinc. The result is a thermoset material with a very high glass transition temperature Tg of up to 400 C, and a very low dielectric constant , providing excellent long term thermal stability at elevated end use temperatures, very good fire, smoke and toxicity performance and specific suitability for printed circuit board s installed in critical electrical devices. The chemistry of the cure reaction is a trimerization of three CN groups to a triazine ring. Because the starting material is a product with two cyanate groups the resulting structure is a 3D polymer network . Product properties can be finetuned by the choice of substituent s in the bisphenolic compound. Bisphenol A and novolac based cyanate esters are the major products, bisphenol F and bisphenol E are also used. The aromatic ring of the bisphenol can be substituted with an allyl ic group for improved toughness of the material. Cyanate esters can also be mixed with bismaleimide s to form BT Epoxy BT resins or with epoxy resins to optimize the end use properties.

BT Epoxy belongs to the group of thermoset resin s used in printed circuit board s PCBs . It is a mixture of epoxy resin , a common raw material for PCBs and BT resins. BT stands for Bismaleimide Triazine resin. This is in turn a mixture of Bismaleimide , which as such is also used as a raw material for PCBs and Cyanate Ester . Three cyano groups of the cyanate ester are trimerized to a triazine ring structure, hence the T in the name. In presence of a bismaleimide the double bond of the maleimide group can copolymerize with the cyano groups to heterocyclic 6 membered aromatic ring structures with two nitrogen atoms pyrimidines . The cure reaction occurs at temperatures up to 250 degrees C, and is catalyzed by strongly basic molecules like Dabco diazabicyclooctane and 4 DMAP 4 dimethylaminopyridin . Products with very high glass transition temperatures Tg up to 300 degrees C and very low dielectric constant can be obtained. These properties make these materials very attractive for use in PCBs.

image Wohler synthesis.gif right The W hler synthesis is the conversion of ammonium cyanate into urea . Ref 1 This chemical reaction was discovered in 1828 by Friedrich W hler in an attempt to synthesize ammonium cyanate. It is considered the starting point of modern organic chemistry . Although the W hler reaction concerns the conversion of ammonium cyanate, this salt only appears as an unstable intermediate. W hler demonstrated the reaction in his original publication with different sets of reactants a combination of cyanic acid and ammonia , a combination of silver cyanate and ammonium chloride , a combination of lead cyanate and ammonia and finally from a combination of mercury cyanate and cyanatic ammonia which is again cyanic acid with ammonia . Ref 2 The reaction can be demonstrated by starting with solution s of potassium cyanate and ammonium chloride which are mixed, heated and cooled again. again what exactly? An additional proof of the chemical transformation is obtained by adding a solution of oxalic acid which forms urea oxalate as a white precipitate .

pseudo Pseudo halogen molecules meaning fake halogen s are inorganic molecules of the general forms Ps Ps or Ps X, where Ps is a pseudohalogen group such as cyanide , cyanate , thiocyanate and others, and X is a true halogen . Not all combinations are known to be stable. Examples of pseudohalogen molecules Examples of symmetrical pseudohalogens Ps Ps include cyanogen CN sub 2 sub , thiocyanogen SCN sub 2 sub , selenorhodane SeCN sub 2 sub , azidodithiocarbonate N sub 3 sub CS sub 2 sub sub 2 sub . Another complex symmetrical pseudohalogen is dicobalt octacarbonyl , Co sub 2 sub CO sub 8 sub . This substance can be considered as a Dimer chemistry dimer of the hypothetical cobalt tetracarbonyl, Co CO sub 4 sub . Examples of non symmetrical pseudohalogens Ps X are cyanogen halide s iodine cyanide ICN , ClCN , BrCN , and other compounds. Sometimes nitrosyl chloride NOCl also is considered as pseudohalogen. Pseudohalides Pseudohalides are the anion s or functional group s of corresponding pseudohalogen groups such as cyanide s, cyanates , isocyanates , rhodanide s i.e. thiocyanates and isothiocyanates , selenorhodanide s, tellurorhodanide s and azide s. A common complex pseudohalide is tetracarbonylcobaltate Co CO sub 4 sub sup sup . The acid Cobalt tetracarbonyl hydride HCo CO sub 4 sub is in fact quite a strong acid , though its low solubility renders it not as strong as the true hydrohalic acid s. The behavior and chemical properties of the above pseudohalides are identical to that of the true halide ions. The presence of the internal double bond s or triple bond s do not appear to affect their chemical behavior. For example, they can form strong acids of the type HX compare HCl to HCo CO sub 4 sub , and they can react with metals to form compounds like MX compare NaCl to NaN sub 3 sub . Nanoclusters of aluminium often referred to as superatom s are sometimes considered to be pseudohalides since they, too, behave chemically as halide ions, forming Al13 Al sub 13 sub I ... more details
