Participants

Reaction Steps

These monomers are commercially available or can be prepared by a simple modification. A very suitable monomer is α,α'-dibromo-2-cyano-p-xylene (see formula V of FIG. 2), which can be prepared by refluxing a mixture of 2,5-dimethylbenzonitryl, N-bromosuccinimide and benzoyl peroxide in carbon tetrachloride for several hours. The solid formed is recrystallized from a mixture of petroleum ether and toluene and subsequently dried under a vacuum. Another suitable monomer is α,α'-dibromo-2-methoxy-p-xylene (see formula VI of FIG. 2), which can be prepared by refluxing a mixture of 2,5-dimethylanisol, N-bromosuccinimide and benzoyl peroxide in carbon tetrachloride in a nitrogen atmosphere for several hours. The solid formed is recrystallized from hexane and subsequently dried under a vacuum.
