Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 41 words
In an article comprising a substrate coated on its surface with a polymer containing polar monomer units, the improvement wherein said monomer units and the main polymer chains of the polymer have a substantially perpendicular orientation with respect to the surface.
Claim 2
Dependent Claim 41 words
In an article comprising a substrate coated on its surface with a polymer containing polar monomer units, the improvement wherein said monomer units and the main polymer chains of the polymer have a substantially perpendicular orientation with respect to the surface.
Claim 3
Dependent Claim 41 words
An article of claim 1, wherein at least about 60% of the monomer units and 60% of the main polymer chains have an orientation with respect to the surface which does not deviate from the perpendicular by more than about 10°.
Claim 4
Dependent Claim 13 words
An article of claim 1, wherein said monomer units have a dipolar alignment.
Claim 5
Dependent Claim 23 words
An article according to claim 1, wherein said polar monomer units possess an electron donor polar group and an electron acceptor polar group.
Claim 6
Dependent Claim 56 words
A process for the preparation of an article according to claim 1, comprising polymerizing cyclic monomers capable of ring-opening polymerization and possessing polar groups in the presence of a polymerization initiator anchored to the substrate surface whereby the main polymer chain of the resultant polymer have a substantially perpendicular orientation with respect to the substrate surface.
Claim 7
Dependent Claim 48 words
A process for the preparation of an article according to claim 1, comprising polymerizing monomers possessing polar groups and then anchoring the resultant polymer to the substrate surface whereby the main polymer chain of the resultant polymer have a substantially perpendicular orientation with respect to the substrate surface.
Claim 8
Dependent Claim 28 words
In 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.
