WebFor polypropylene, this reference value is 207 J/g. This yields an estimated percent crystallinity of 51.7% for the as-received polypropylene film. The measurement of the glass transition event, Tg, of polypropylene is generally considered difficult by DSC given that the transition is weak. However, a DSC with high WebThe effect of different catalysts on the thermal degradation of propylene (PP) has been studied by thermogravimetric analysis (TGA). TGA experiments were used to compare the activity of different catalysts towards PP degradation. All the hydrocracking (HC) catalysts enhanced the pyrolysis of PP.
