Patent ID: 6852793

Claim:
Polymeric compositions comprising: one or more aromatic-based copolymers of two or more monomers at least one of which being aromatic, wherein said two or more monomers are selected from the group consisting of C 1-10 alkyl methacrylate, C 1-10 alkyl acrylate, C 6-40 arylalkyl acrylate and C 6-40 arylalkyl methacrylate polymerized with one or more hydrophilic monomers selected from the group consisting of N,N-dimethylacrylamide, glycerol methacrylate and N-vinylpyrrolidinone and optionally with one or more monomers selected from the group consisting of aromatic-based monomers and hydrophobic monomers, to have a water content greater than 4.5 percent by weight but less than 15 percent by weight, a refractive index of approximately 1.45 or greater and a elongation of approximately 80 percent or greater.
