PY - 2020/07/01 Y2 - 2024/03/29 TI - A COMPARATIVE STUDY OF ROLES PLAYED BY ALUMINUM TRIBROMIDE AND ALUMINUM ACETYLACETONATE ON THE THERMAL DEGRADATION OF PMMA BY SIMULTANEOUS THERMOANALYTICAL TECHNIQUES JF - The Nucleus JA - The Nucleus VL - 45 IS - 1-2 SE - Articles DO - UR - http://thenucleuspak.org.pk/index.php/Nucleus/article/view/999 SP - 63-70 AB - <p>Blends of poly(methyl methacrylate) (PMMA) were prepared with aluminum tribromide (AlBr3) and aluminum<br />acetylacetonate (Al(acac)3)in definite ratios. Thermal studies (TG-DTG-DTA) of polymer and blends with both additives<br />were carried out in inert atmosphere to investigate the mode of degradation and the effects of stability/destability on<br />either component. The addition of compounds in polymer resulted early decompositions. The intermediates formed<br />during decomposition were also identified. The possible explanation of the thermal degradation reactions is advanced<br />on the basis of results gathered. The apparent activation energy (Eo) and order of reaction (n) of the pyrolitic reactions<br />were determined by Horowitz and Metzger method from the corresponding TG curves.</p> ER -
