Studies on bismaleimides and related materials: 1. DMTA investigation of the reaction of bismaleimides with m-tolualdehyde azine and 3,5-dimethylpyridine N-oxide: an approach to the design of novel reactive diluents was written by Davidson, G.;Soutar, I.;Preston, P. N.;Shah, V. K.;Simpson, S. W.;Stewart, N. J.. And the article was included in Polymer in 1994.Application of 3718-65-8 This article mentions the following:
Dynamic mech. thermal anal. (DMTA) 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. Addnl. chem. 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 In the experiment, the researchers used many compounds, for example, 3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8Application of 3718-65-8).
3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Application of 3718-65-8
