    Abstract: The invention provides a method and apparatus for continuously feeding wet gel polymers into a drying step of a dry polymer synthesis operation. A number of pistons are arranged having inner chambers through which monomers and other reagents are fed and polymerized into wet gel polymers. Each piston operates according to a coordinated schedule so that as one piston finishes extruding polymer into the drying step, a second piston has completed polymerizing more polymer and continues to feed more polymer without interruption. The then finished is re-fed more reagents so as to be ready again when needed next. As a result, cost effective continuous feeding can be achieved without the contamination and impurity problems that have plagued previous attempts to accomplish this.

  • Patent number: 8658749
    Abstract: Biocompatible polymers are manufactured to include an ammo acid mimetic monomer and one or more hydrophobic acrylate monomers. The amino acid mimetic monomers are selected to mimic the side chain of the amino acids asparagine or glutamine. The amino acid mimetic monomer can be a methacryloyl or acryloyl derivative of 2-hydroxyacetamide, 3-hydroxypropionamide, alaninamide, lactamide, or glycinamide. These amide functional groups offer the advantage of moderate hydrophilicity with little chemical reactivity. The amino acid mimetic monomer can be copolymerized with one or more hydrophobic acrylate monomers to obtain desired coating properties.

  • Patent number: 8637589
    Abstract: In one aspect, the invention relates to silicone prepolymer compositions comprising a silicone prepolymer and a solvent. A soluble silicone prepolymer can be provided having increased average silicon content, thereby attaining a desired oxygen permeability. A solvent can be provided with a desired balance between hydrophilicity and hydrophobicity by selection and modification of the solvent molecular structure, resulting in molded polymer films and articles that exhibit minimal or nonexistent eye irritation and exhibit highly transparent products. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
