Trifunctional cyanate esters, polymers thereof; use and preparation thereof

摘要

Trisphenol PA tricyanate, prepolymers and crosslinked polymers thereof are provided. Blends of trifunctional cyanates and fluorinated or non-fluorinated difunctional cyanate are provided. The crosslinked polymers exhibit low dielectric loss properties and high glass transition temperatures and are suitable as the matrix material for structural composites including printed circuit boards.
