Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
62 words
In an article comprising a substrate coated on its surface with a polymer layer containing polar monomer units, the improvement wherein the monomer units and main polymer chains of the polymer originating from cyclic monomers have a substantially parallel orientation with respect to the surface due to the cyclic structure of the monomers and wherein said monomer units have a dipolar arrangement.
Claim 2
Dependent Claim
62 words
In an article comprising a substrate coated on its surface with a polymer layer containing polar monomer units, the improvement wherein the monomer units and main polymer chains of the polymer originating from cyclic monomers have a substantially parallel orientation with respect to the surface due to the cyclic structure of the monomers and wherein said monomer units have a dipolar arrangement.
Claim 3
Dependent Claim
34 words
An article of claim 1, wherein at least about 60% of said monomer units and 60% of the main polymer chains have an angular deviation from the horizontal of not more than about 10°.
Claim 4
Dependent Claim
24 words
An article according to claim 1, wherein said cyclic polar monomer units contain an electron donor polar group and an electron acceptor polar group.
Claim 5
Dependent Claim
35 words
A process for the preparation of an article according to claim 1, comprising polymerizing said monomer units by ring-opening polymerization in a desired direction of polymer growth by subjecting the monomer layer to zonal irradiation.
Claim 6
Dependent Claim
27 words
A method for achieving a non-linear optical effect by impinging light on a surface, the improvement comprising impinging light on a coated surface according to claim 1.
