Summary
Poly(2,6-dimethyl-1,4-phenylene)oxide crystals obtained from 0.1%α-pinene solutions by isothermal growth at temperatures from 80–90 as well as 100 °C, were investigated by optical and X-ray diffraction techniques. A study has been made by differential scanning calorimetry in order to measure the melting point, glass transition and melting point depression temperatures of mixtures of the polymer withα-chloro-naphthalene.
The densities of the dry mats of single crystals were measured by a flotation method.
Zusammenfassung
Poly(2,6-dimethyl-1,4-phenylen)oxid Kristalle, die aus 0,1% igenα-Pinen-Lösungen durch isothermes Wachstum bei Temperaturen von 80–90 sowie 100 °C erhalten wurden, wurden optisch und röntgenographisch untersucht. Mit der Differential-scanning-Kalorimetrie ergaben sich die Werte des Schmelzpunkts, der Glastemperatur und der Schmelzpunktdepressionen von Mischungen des Polymeren mitα-Chlornaphthalin. Die Dichten der trockenen Matten aus Einkristallen wurde mit der Flotationsmethode gemessen.
