Alkyl-substituted poly(ary1 ether ketone)s (PEKs), having more than two alkyl substituents per repeat unit, were synthesized by nucleophilic substitution reaction of 1,l'-(p-phenylenedioxy)bis[ 2-methyl-4-(fluorobenzoyl)benzene] with an aromatic diol of different structure in the presence of a base.
## Abstract The kinetics of the thermal rearrangement 4βethylβ3,5βdiphenylβ4__H__β1,2,4βtriazoles, **1**, to the corresponding 1βethylβ3,5βdiphenylβ1βalkylβ1__H__β1,2,4βtriazoles, **2**, was studied in 15βCrownβ5 and octadecane at 330 Β°C. The reaction was very slow in octadecane but proceed well in
