In recent years, acrylate binders were widely used in PBX production High loading of explosives and processability are the prominent features of these binders that researchers are trying to improve the energetic properties of these binders. In this research, a novel energetic binder of poly (2,4,6-trinitrophenylacetal acrylate) (PATNP) was synthesized through acetalization reaction Poly(glycerol monoacrylate) with 2,4,6-trinitrophenyl acetaldehyde in the presence of p-toluene sulfonic acid (PTSA) as the catalyst. The polymer structure was confirmed using 1H NMR and FT-IR. Thermal anal. obtained from the TGA curve of polymer shows that the addition of TNT derivatives significantly changes the thermal decomposition processes. In the TGA curve of PATNP, two main weight losses were observed with a decomposition percentage of 38 and 37%. The glass transition temperatures (Tg) of poly(glycerol monoacrylate) and PATNP were measured by DSC, and their Tg were obtained at -51° and -43°, resp. The heat of formation (HOF) and the HOMO-LUMO gap of PATNP was calculated using DFT computational method and compared with HTPB, AHTPB, and GAP binders. The HOF of PATNP for the monomer and dimer was obtained as 70.67 and 263.26 J/g, resp. The HOMO-LUMO gap for TNPA and PATNP was calculated at 3.7296 and 4.152 eV, resp. The obtained energetic polymer can have a potential application as the binder of PBXs. In the experimental materials used by the author, we found N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5Recommanded Product: 4637-24-5)
N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5) belongs to anime. Aniline, ethanolamines, and several other amines are major industrial commodities used in making rubber, dyes, pharmaceuticals, and synthetic resins and fibres and for a host of other applications. Most of the numerous methods for the preparation of amines may be broadly divided into two groups: (1) chemical reduction (replacement of oxygen with hydrogen atoms in the molecule) of members of several other classes of organic nitrogen compounds and (2) reactions of ammonia or amines with organic compounds.Recommanded Product: 4637-24-5
