ABSTRACT:
The invention provides a method for making optionally active polymers having a carbon-to-carbon backbone chain and pendant "transducer" groups having an azo linkage which involves azo-coupling, in homogeneous solution, a carbon-to-carbon backbone polymer having pendant groups terminating in an aromatic group with an aromatic diazonium salt, and recovering the resultant reaction product.
