Abstract
In this paper the possibilities of generating static and dynamic birefringence in polymers are discussed with reference to results from the authors' laboratories. Orientation in polymers can be achieved either by orientation of monomers and polymerization of the oriented molecules under maintenance of the orientation or by orientation of isotropic polymers under the influence of physical forces. Copolymers of positive and negative birefringent components (allyl and methacrylic monomers) have been synthesized which show either an achromatic birefringent behavior or are without any birefringence. In addition, special allyl polymers have been studied which have very high stress-optical coefficients and can be used as acousto-optical modulators or as sensors.
