Chloroanisole‐1,2‐dichloroethane resins and their thermal stability

Abstract

Resins were prepared by Friedel-Craft polymerization of chloroanisoles and 1,2-dichloroethane. The kinetic parameters were evaluated by the methods of Chatterjee, Freeman-Anderson, Broido, Flynn and Wall, Reich, and Kissinger from the TG and DTA thermograms, respectively. The energy of activation, EA decreased with increasing heating rates. This was explained on the basis of flexible nature and rearrangement of molecules.

Nach den Methoden von Chatterjee, Freeman-Anderson, Broido, Flynn und Wall, Reich und Kissinger wurden aus TG-und DTA-Thermogrammen die kinetischen Parameter bestimmt. Die Aktivierungsenergie EA wurde mit steigender Heizrate geringer, was auf der Basis der Flexibilitat und der Umgruppierung der Molekiile erklart wird. 4 cd ! 2 "' 9, 76 cd A 2. cd A = cd A '9,

Yield Attributes and Yield of Summer Pearl Millet as Influenced by Cultivars and Integrated Nutrient Management

“…Use of bio-fertilizer (Azospirillum + PSB) led to higher availability of N and P as well as promoted the root growth, which promoted yield attributes characters. Corroborative results have also been reported by Lakum et al, (2011) andPatel et al, (2016), Bana et al, (2012).…”
