The effect of sample molecular weight on the glass transition temperature has been examined for isotactic, stereoblock and atactic polypropylene samples. Asymptotic values of T 9 (∞) (isotactic) = 272°K, T 9 (∞) (atactic) = 266°K, and T g (∞) (stereoblock) = 266°K were ...
12.6 GLASS TRANSITION TEMPERATURE Metal acrylic acid complexes were grafted, in the presence of dicumyl peroxide used as a free radical initiator, onto polypropylene. The glass transition temperature, Tg, and the melting temperature, Tm, were affected by the metal used.1 Only copper causes a decre...

What is the feedstock for manufacturing polypropylene? What is the freezing point of Salol? What liquid is used to test for carbon dioxide? What are the properties of plastic? What does temperature measure? What is the refractive index of methanol?
One- and two-dimensional (2D) deuteron NMR experiments in high-pressure NMR equipment have been performed in an investigation of the effect of pressure (up to 5000 bar) on the slow chain dynamics in atactic deuterated polypropylene, above its glass-transition temperature T g( p). The slow ...
