Additives and modifiers for cyanate ester resins [PDF]

open access: yes, 1994
Other chapters in this book are concerned with the mechanism of cure of cyanate esters (CE), kinetics, processing and the structure-properties relationships. However, all these results mainly concern pure cyanates. The major uses of these polymers are in the electronics industry (printed circuitboards) and in the aerospace industry with a market of 70 ...

Cooperative Photometallobiocatalysis: Nonheme Fe Enzyme‐Catalyzed Enantioconvergent Radical Decarboxylative Azidation, Thiocyanation, and Isocyanation of Redox‐Active Esters

open access: yesAngewandte Chemie, EarlyView.
Through the directed evolution of an underexploited nonheme Fe extradiol dioxygenase, we developed a unified cooperative photobiocatalytic strategy to allow for three types of enantioconvergent radical transformations, including azidation, thiocyanation, and isocyanation.

Preparation, Cure, and Characterization of Cyanate Ester-Epoxy Blends [PDF]

open access: yes, 2022
Cyanate ester resins are often blended with lower cost epoxy monomers in order to modify the cost, toughness, and processing characteristics. There are also several choices of catalysts that can be used to improve processing, namely by reducing the cure ...
