摘要： A star-blocked polymeric material based on polyethylene glycol and having a uniform distribution of both hydroxy and amine functional groups throughout the polymeric material is described. The polymeric material, known as HYDRA (hydroxy and amine functionalized resin), is prepared by forming a polyimine compound by reacting an aldehyde and an amine. The polyimine is then reacted with a reducing agent to form a star-blocked polymeric material. HYDRA resins can be used, for example, as solid supports for organic synthesis, for enzymatic assays, for immobilization of biomolecules, for controlled release of drugs, and for chromatographic separations.

摘要： A conductive resin composition includes between 40 and 140 parts by weight of reactive epoxy resin, between 15 and 40 parts by weight of a reactive monofunctional glycidyl material, a cure accelerant, and 40 to 200 parts by weight of a conductive particulate material. The conductive resin composition forms a defect-free conductive coating on a substrate after mixing a one part epoxy resin composition under vacuum at a temperature insufficient to induce thermal cure. Adding a liquid epoxy resin to the one part epoxy resin composition to form a mixture combining 40 to 200 parts by weight of conductive particulate with the mixture and dispersing the combined conductive particulate and the mixture under vacuum until a homogeneous conductive resin paste results where the dispersing time for the combined conductive particulate and the mixture under vacuum is greater than or equal to the period of time of vacuum mixing the liquid one part epoxy composition.
