Soluble maleimide prepolymers containing 1,3,5-triazine group as composite resin matrixes. Part 1. Synthesis and characterization was written by Dolui, Swapan K.;Maiti, Sukumar. And the article was included in Journal of Polymer Materials in 1991.Recommanded Product: 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine The following contents are mentioned in the article:
Low-mol.-weight amine-terminated monomaleimide prepolymers containing 1,3,5-triazine groups were synthesized by cocondensing benzophenonetetracarboxylic dianhydride, diamines having 1,3,5-triazine groups, and maleic anhydride. These low-mol.-weight reactive prepolymers were soluble in low-boiling solvents such as CHCl3, THF, etc. These were characterized by elemental (N) analyses, IR, and NMR spectroscopy, vapor-pressure osmometry, and viscosity. On heating at 180-190° these prepolymers underwent simultaneous chain extension by Michael addition reaction and crosslinking by mutual reaction between their amine-terminated and maleimide-terminated ends. The cured polyimides were thermally stable and their thermal behavior was studied by TGA, DTA, and isothermal aging at 200-250°. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Recommanded Product: 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Recommanded Product: 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine
