  • Patent number: 9012415
    Abstract: This invention refers to photo-crosslinked hydrogel materials based in gellan gum suitable for tissue engineering and regenerative medicine applications or as drug delivery systems. Formulations of gellan gum with different degrees of acylation serve as precursor material for insertion of a polymerizable moiety. The materials are capable of free radical polymerization with a photo-initiator at mild temperatures and exposure to ultraviolet light, enabling control of reticulation and withstanding the encapsulation of human and animal cells and/or drugs, and any combination thereof. The physicochemical and biological properties can be adjusted by combining different formulations of gellan gum and reaction conditions.

    Abstract: A radiation crosslinked (50 kGy), pressure-treated UHMWPE material has been developed by applying compressive force on a crosslinked polymer in a direction orthogonal to an axial direction. The deformed material is then cooled while held in a deformed state. The resulting material is anisotropic, with enhanced strength oriented along the axial direction. The directionally engineered material is oxidatively stable even after four weeks of accelerated aging in a pressure vessel containing five atmospheres of oxygen (ASTM F2003). Because of its oxidative stability, the deformation processed material is a suitable candidate for air-permeable packaging and gas sterilization, which has thus far been reserved for remelted highly crosslinked UHMWPEs.

  • Patent number: 6830782
    Abstract: A method of modifying a polymeric material which comprises the steps of activation-treatment and a hydrophilic polymer-treatment, or comprises the steps of activation-treatment, a hydrophilic polymer-treatment, and monomer grafting in this order, or comprises the step of a solvent-treatment followed by these steps. Thus, the polymeric material, e.g., polyolefin, is improved in hydrophilicity, adhesion, etc. without lowering the practical strength thereof. The polymeric material thus improved in adhesion and other properties can be used in many applications where water absorption and adhesion are required, such as an absorption material, e.g., a wiping/cleansing material, a water retention material, a material for microorganism culture media, a separator for batteries (or cells), a synthetic paper, a filter medium, a textile product for clothing, a medical/sanitary/cosmetic supply, and reinforcing fibers for composite materials.

  • Patent number: 6821108
    Abstract: The invention is concerned with the problem that with known plastic casting moulds, especially those of polypropylene, the lenses produced with these moulds have a slippery surface. The invention solves this problem through the use of polymers which are notable for their very low oxygen permeability.

  • Patent number: 6800670
    Abstract: The present invention discloses methods for enhancing the wear-resistance of polymers, the resulting polymers, and in vivo implants made from such polymers. One aspect of this invention presents a method whereby a polymer is irradiated, preferably with gamma radiation, then thermally treated, such as by remelting of annealing. The resulting polymeric composition preferably has its most oxidized surface layer removed. Another aspect of the invention presents a general method for optimizing the wear resistance and desirable physical and/or chemical properties of a polymer by crosslinking and thermally treating it. The resulting polymeric compositions is wear-resistant and may be fabricated into an in vivo implant.

  • Publication number: 20030027885
    Abstract: The novel photo-cross-linkable polymers are suitable as coating materials. The photo-cross-linkable polymers contain a biphenylene unit, which can be dimerized by exposure. Attached to the biphenyl unit are side chains of a polymer with a high temperature resistance and a high chemical stability. Through exposure, the biphenylene units dimerize, whereby the polymers are spatially cross-linked.
