ABSTRACT:
Disclosed is a class of polymers comprising recurring units of the formula ##STR1## where Mu is a divalent radical having the formula ##STR2## where each of D, D', E and E' is hydrogen, alkyl or substituted-alkyl; and Az is a divalent radical having the formula ##STR3## where each of R and R' is hydrogen, alkyl, aryl, alkaryl or aralkyl and W is a single bond, alkylene or alkenylene; or Az is a divalent radical having the formula ##STR4## where each of Y and Y' represent the atoms necessary to complete a piperazine or substituted-piperazine radical.
Molecularly oriented polymers of the invention exhibit birefringence and can be utilized in filter, polarizing and other optical devices.
