Abstract

Dynamic mechanical thermal analysis (d.m.t.a.) profiles have been recorded for interaction of m-tolualdehyde azine and 3,5-dimethylpyridine N-oxide with the bismaleimide (BMI) derived from 3,3-diaminobenzophenone. Additional chemical events for each system are recognized at temperatures below the conventional BMI curing region. Resins prepared from the BMI/azine and BMI N-oxide systems have lower thermal stability than the neat resin but differences are moderate at low additive concentrations. © 1994.
