MODIFIED CYANATE ESTER-BASED HARDENING RESIN COMPOSITION FOR LAMINATED SHEET, PREPREG AND LAMINATED SHEET USING THE SAME COMPOSITION

Japanese Patent JP3261076

B2

PROBLEM TO BE SOLVED: To obtain the subject composition useful for laminated sheets good in resistance to heat and required to show low loss in a high frequency range by including a specific cyanate ester, specific monovalent phenol, polyphenylene ether resin, flame retardant unreactive with the cyanate ester, and specific catalyst.
SOLUTION: This composition is obtained by including (A) 100 pts.wt. of a cyanate ester shown by formula I (R1 is CH2 or the like; and R2 and R3 are each H or the like), e.g. 2,2'-bis(4-cyanatophenyl) propane, (B) 4 to 30 pts.wt. of a monovalent phenol shown by formula II (R4 and R5 are each H or the like), (C) 5 to 30 pts.wt. of a polyphenylene ether resin, (D) 5 to 30 pts.wt., per 100 pts.wt. of the components A, B and C, of a flame retardant unreactive with the cyanate ester above, and (E) 1 to 300 wt. ppm, per gram of the component A, of a metal-based reaction catalyst (e.g. a complex of manganese).
