Abstract
In this study the author investigated the effect of non-acidic porous solid (silicalite) on the thermal degradation behavior of polypropylene and polystyrene, and found that silicalite affects the thermal degradation behavior of polypropylene and polystyrene as well as polyethylene, respectively. And for comparison with silicalite, the thermal degradation behavior with silica-alumina was studied.
Experimental results obtained by the continuous reactor showed that not only the configuration of porous solids affected the thermal degradation behavior of polymer, but also the configuration of macromolecules affected it.
