COA of Formula: C8H11NO2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1-(tert-Butyl)-1H-pyrrole-2,5-dione, is researched, Molecular C8H11NO2, CAS is 4144-22-3, about Thermal degradation of vinylidene chloride/vinyl chloride copolymers in the presence of N-substituted maleimides. Author is Howell, Bob A.; Zhang, Jin.
As a consequence of their excellent barrier properties vinyl chloride/vinylidene chloride copolymers have long been prominent in the flexible packaging market. While these polymers possess a number of superior characteristics, they tend to undergo thermally induced degradative dehydrochlorination at process temperatures This degradation must be controlled to permit processing of the polymers. Three series of N-substituted maleimides (N-alkyl-, N-aralkyl, and N-aryl) were synthesized, characterized spectroscopically, and evaluated as potential stabilizers for a standard vinyl chloride/vinylidene chloride (85 mass %) copolymer. As surface blends with the polymer, these compounds are ineffective as stabilizers. However, significant stabilization may be achieved by pretreatment of the polymer with N-substituted maleimides. The most effective stabilization of the polymer is afforded by N-aralkyl- or N-arylmaleimides, most notably, N-benzylmaleimide and N-p-methoxyphenylmaleimide.
From this literature《Thermal degradation of vinylidene chloride/vinyl chloride copolymers in the presence of N-substituted maleimides》,we know some information about this compound(4144-22-3)COA of Formula: C8H11NO2, but this is not all information, there are many literatures related to this compound(4144-22-3).
