  • Patent number: 8722814
    Abstract: Polyglycerol carboxylic acid esters are made by reaction of a, typically C2 to C30, particularly C6 to C22, carboxylic acid with glycerol carbonate, particularly with base catalyst, and desirably at temperatures from 170° C. to 250° C. Other carbonates e.g. cyclic diol carbonates such as ethylene or propylene carbonates, may be used in combination with the glycerol carbonate to make novel mixed polymeric esters. The molar ratio of carboxylic acid group to glycerol carbonate is typically from 2 to 30, but can be up to 100. The base catalyst is desirably alkali metal hydroxide, carbonate or alkoxide. The reaction is desirably carried out in an inert atmosphere, and reducing agent such as phosphorous acid, hypophosphorous acid or borohydride and/or activated carbon, may be included to improve product color.

  • Patent number: 8691882
    Abstract: Provided are an organic-inorganic hybrid scaffold with surface-immobilized nano-hydroxyapatite, and a method for the fabrication thereof. The scaffold is fabricated by reacting an acid group present on a surface of nano-hydroxyapatite with a primary amine present on a surface of a polymer support in the presence of EDC (1-ethyl-3-dimethylaminopropyl carbodiimide) to immobilize nano-hydroxyapatite onto the surface of the polymer support. The surface of nano-hydroxyapatite is previously grafted with poly(ethylene glycol methacrylate phosphate) (PolyEGMP) having phosphonic acid functionality or with a polymer having carboxylic acid functionality.
