反応手順
m-Aminobenzoic acid hydrazide (4 parts) is blended with methylglycolate and heated to 60° C. to obtain a solution. A mixture of 4,4'-bismaleimidodiphenylmethane (70 parts), 2,4-bismaleimidotoluene (30 parts) and 1,6-bismaleimido(2,2,4-trimethylhexane (2 parts) and methylglycolate was added and the mixture heated to 120° C. to give a homogeneous solution. The solvent was stripped off to give a molten BMI resin to which 60 parts of the product of Example 12 was added and melt blended. The homogeneous melt was degassed in vacuum, cast into a parallel epipedic mould and cured for 2 hours at 170° C., plus 4 hours at 210° C., at a pressure of 4 bars. After demoulding, the casting is post-cured for 5 hours at 240° C.
