Abstract : Block copolymers of hydrophobic and hydrophilic acrylates were to be made and tested for control of mineralization by calcium oxalate. Acrylate copolymers in solution inhibited crystal growth to an extent dependent on their acid content but not dependent on the architecture. Solid films of acrylate polymers became mineralized when exposed to oxalate solutions. This effect was very dependent on the structure of the polymer. Methods were also developed for forming inorganic layers on polymer films by overlaying two polymers, each containing solubilized precipitants. Reaction and precipitation would occur at the film/film interface. Cross-linked methacrylic acid films could be templated with rigid molecules such as caffeine, and then would be absorb the templated molecule selectively from solution. Methods were also developed for coupling short protein chains to acrylate polymers as a route to combining biochemical specificity with localization on inorganic surfaces.
