High purity monomer for contact lens applications . High purity carboxylated
monomers increase the hydrophilicity in polymers and provide crosslinking sites
for divalent ions (e .g . Zn++) . Polysciences, Inc . offers both methacrylic acid in high
purity (99 .9%) and a longer chain analog, Beta-Carboxyethyl acrylate, (99%)
