Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
122 words
A polymeric composition having a molecular weight in the range between about 500 and 2,000,000 and consisting essentially of recurring monomer units corresponding to the formula: ##STR10## wherein R is a member selected from the group consisting of aliphatic, alicyclic, heterocyclic and aromatic hydrocarbon radicals containing between 1 and about 10 carbon atoms; R 1 and R 2 are members independently selected from the group consisting of hydrogen and aliphatic, alicyclic, heterocyclic and aromatic hydrocarbon radicals, or R 1 and R 2 taken together with the connecting elements form an alicyclic structure, and wherein the total number of carbon atoms in R 1 and R 2 collectively does not exceed about 20; and n is an integer between 2 and about 10,000.
Claim 2
Dependent Claim
122 words
