Patent ID: 6906166

Claim:
A composition of matter comprising a polymer of the general structure: wherein the R1 substituents are independently selected from the group consisting of hydrogen, alkyl groups, alkoxy groups, and aryl groups; the R2 substituents are independently selected from the group consisting of hydrogen, alkyl groups, alkoxy groups, and aryl groups; the R3 substituents are independently selected from the group consisting of hydrogen, alkyl groups, alkoxy groups, and aryl groups; the R4 substituents are independently selected from the group consisting of hydrogen, alkyl groups, alkoxy groups, and aryl groups; wherein bonds A and B may be either ortho or para with respect to the pyridyl nitrogen; wherein bonds C and D may independently be either ortho, meta or para with respect one another; wherein bonds E and F may be either ortho, meta or para with respect one another; wherein bonds G and H may be either ortho, meta or para with respect one another; wherein Y may be a moiety selected from the group consisting of —(CH 2 ) x —, —(CH 2 ) x O—, —O(CH 2 ) x — and —O(CH 2 ) x O— wherein x is an integer in the range of 1 to 15 inclusive; wherein Z may be a moiety selected from the group consisting of —(CH 2 ) x —, —(CH 2 ) x O—, —O(CH 2 ) x — and —O(CH 2 ) x O— wherein x is an integer in the range of 1 to 15 inclusive; and wherein n is an integer greater than 1.
