Thermal Degradation of Terpolymer Derived from 2, 4-dihydroxyacetophenone, propylenediamine and Formaldehyde
Journal Title: World Journal of Pharmaceutical Sciences - Year 2017, Vol 5, Issue 7
Abstract
The terpolymer (2,4-DHAPrDF) was synthesized by condensation of 2,4-dihydroxyacetophenone and paraphenylene diamine with formaldehyde in the presence of 2 M HCl as a catalyst at 130 ± 2 OC for 5 h. The terpolymer 2,4-DHAPrDF was characterized by elemental analysis FTIR, 1HNMR and UV-Visible spectroscopy. The thermal decomposition behavior 2,4-DHAPrDF was studied using thermogravimetric analysis (TGA/DTA) in a static oxygen atmosphere at a heating rate 10 OC /min. Freeman-Carroll, Sharp-Wentworth methods were used to calculate thermal activation energy (Ea), the order of reaction (n), entropy change (ΔS) Synthesized terpolymer resin shown moderate antibacterial activity and porous morphology.
