Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
40 words
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.
Claim 2
Dependent Claim
40 words
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.
Claim 3
Dependent Claim
28 words
The process according to claim 1, wherein predetermined regions of the polymeric material are irradiated with light polarized in a direction other than that of the linearly-polarized light.
Claim 4
Dependent Claim
29 words
The process according to claim 1, wherein a predetermined region of the polymeric material is irradiated with linearly-polarized light, and a different predetermined region is irradiated with non-polarized light.
