Abstract
Optical devices including a molecularly oriented highly birefringent polymer are disclosed. The devices include molecularly oriented polymers comprising recurring units which exhibit a distribution of high electron density about the long axes of the polymer and the recurring units thereof. Transparent birefringent polymers comprising a plurality of recurring units having a substantially cylindrical distribution of electron density about the long axis of such units and the chain-extended polymers are included in optical devices and articles. The polymers exhibit high birefringence and simulate in a polymer the optical properties of a uniaxial crystal.
Claims56
An optical device comprising a transparent molecularly oriented highly birefringent polymer, said highly birefringent polymer comprising repeating molecular units exhibiting high electron density substantially cylindrically distributed about the long axes of the polymer and the repeating units thereof, said highly birefringent polymer being substantially optically uniaxial exhibiting only two indices of refraction.
