Pentamethylbenzyl chloride

For example, hexamethyl (Dewar benzene) is converted to hexamethylbenzene by a radical-ion chain reaction initiated by PET to the sensitizer [50]. A similar PET induced rearrangement occurs in the transformation of a chloromethylenebicy-clo[2.2.0]hexene to pentamethylbenzyl chloride [49].

Mm acetate if up to 14% of the acrylic acid units are neutralized. The value of Tg increases with a number of reacted units as a result of an increase in rigidity of separate rings and a decrease in mobility of the chain as a whole (i.e., p-relaxation is almost independent of the metal content). An increase of Tg is also observed for (r -pentamethylbenzyl)(ri -cyclopentadienyl)iron bonding to poly(vinyl chloride) (PVC) and in many other cases.
