NOVEL THERMOSETTING CYANATE RESIN AND PREPARING METHOD

摘要

PURPOSE: A cyanate resin is provided to avoid the generation of an OH group in a curing reaction and to ensure an improved heat resistance, coefficient of thermal expansion, low moisture absorbency and low permittivity through a specific structure having low coefficient of thermal expansion. CONSTITUTION: A cyanate resin is represented by one of chemical formulas 1-3. In chemical formulas 1, 2 and 3, the core structure of A and B is selected from the group consisting of a bisphenol-A structure, a biphenyl structure, a naphthalene structure, a cardo structure, an anthracene structure, a polyaromatic structure, and a liquid crystal compound structure. In chemical formula 1, the number(n) of a repeating unit is an integer of 1-10. In chemical formula 3, the number(m) of a repeating unit is an integer of 1-10.
