Abstract
An oriented photopolymer is a polymer where photomodification is initiated by irradiation with plane-polarized light and where the molecular configuration has a preferred orientation as a result of linear polarization. These polymers have optically anisotropic and other novel properties.
Claims3
A process for the manufacture of an oriented photopolymer, which comprises:
- a) providing a layer of a photo-polymerizable, optically isotropic polymeric material, and
- b) orienting and polymerizing said layer by irradiating it with linearly-polarized light to obtain the oriented photopolymer.
