Studies on cure chemistry of new acetylenic resins

摘要: Cure studies of arylacetylene-terminated resins are described to gain some fundamental understanding the influence various structural aspects a molecule on its cure chemistry. Of particular interest effects number acetylenic substituents aromatic ring and their relative positions one another. Activation energy (E) reaction as calculated from dynamic DSC analysis reveals that there is direct correlation between activation stability radicals formed by thermal initiation. Based model coumpound studies, it evident resonance stabilization contributes significantly lowering values
