ABSTRACT:
Dicyanato diphenyl fluorinated alkane resin precursor compositions are modified by the addition of minor predetermined amounts of aromatic diepoxides having high epoxide equivalent weights in order to reduce the curing temperature of prepregs and laminates, such as circuit boards, while retaining low dielectric constants, heat stability and high flame retardance.
