  • Patent number: 6471876
    Abstract: Filtration media having germicidal properties for use in filtering particles and deactivating, removing and/or destroying microorganisms from a feed liquid passing therethrough. The filtration media includes an effective amount of a germicidal chemically grafted and covalently bonded to a surface of the media. The germicidal grafted filter media is prepared by contacting the media with a grafting solution comprising an anionic monomer, a catalyst, a graft initiator and a germicide and subsequently curing tile media at an elevated temperature to chemically graft a polymerized salt of the polymerizable anionic monomer and the cationic germicide onto a surface of the media. Filter media suitable for use in the present invention include ceramic spheroids, hollow glass spheres, polymeric type media and thermoset coated glass spheres.

  • Publication number: 20020069777
    Abstract: A method of forming a photopolymer layer on a printing substrate (e.g., flexographic printing sleeves and cylinders) is provided. The method includes providing a photopolymer composition that contains a photopolymer and at least one monomer bonded to the photopolymer. The monomer can help reduce the hardness of the resulting photopolymer composition. In addition, the method also includes spraying the photopolymer composition onto a rotating generally cylindrical surface of the printing substrate. In one embodiment, the sprayed photopolymer composition is then cured. The resulting photopolymer layer is seamless and continuous and, in some embodiments, has a hardness of between about 50 to about 70 Shore A.

  • Patent number: 6352780
    Abstract: The present invention relates to a polymeric coating composition for application onto glass substrates for anti-reflective properties. The coating is provided via chemical grafting that involves the use of monomers and/or prepolymers, catalyst, and graft initiator and when applied onto the surface of the glass substrate forms a polymeric film chemically bonded to the glass with excellent adhesion. This coating can reduce the reflectance of the coated glass surface to as close to zero as possible, thus maximizing transmittance and providing resistance to abrasion, water/chemical attack, and UV degradation.

  • Patent number: 5888578
    Abstract: A flavored toothpaste composition is bonded to the bristles of a disposable toothbrush by a process which involves the chemical grafting and polymerizing of selected monomers and prepolymers to the bristles via a free radical mechanism. This process locks in the flavor until the product can be utilized. When the toothpaste is brought into contact with an aqueous medium, such as saliva in the oral cavity, the toothpaste dissolves thereby releasing the desired flavor to the teeth and oral cavity.

  • Patent number: 5763557
    Abstract: The invention relates to the chemical bonding of a polymer/or polymers onto non-metallic substrates such as cellophane by ultrasonic techniques. The cellophane film is preactivated by contacting with silver nitrate solution followed by treatment with potassium hydroxide solution whereby particles of silver and silver oxide are uniformly distributed, in situ, over the surface of cellophane film. The pretreated cellophane film when contacted with grafting solution, that contains monomers, prepolymers, catalyst, graft initiator and other ingredients of the composition, which is being agitated with ultrasonic energy results in polymerization of monomer/prepolymer onto the surface of the cellophane film.

  • Patent number: 5741548
    Abstract: This invention relates to a polymeric composition for application onto Reemay and Satin acetate fabric for laser printability with a high level (90% or greater readability of printed characters, washability and enzyme rejection/retardation. The polymeric composition is applied by chemical grafting that involves the use of monomers/prepolymers, catalyst, graft initiator and other ingredients of the composition. The coating thus developed and subsequently applied to Reemay and Satin acetate fabric allows to undergo graft polymerization thereby forming a polymeric film which is chemically bonded to the fabric substrate with strong adhesion. The chemically grafted fabric is highly durable and permanent in terms of distinct legibility of the printed characters on the substrate after 55 launderings or 25 dry cleanings and has excellent level or enzyme rejection/retardation when the coated fabric with laser printed characters are subjected to an enzyme wash process.

  • Patent number: 5552472
    Abstract: A solution for forming a graft substrate containing a graft initiator, a catalyst for activating the graft initiator, a first component of water dispersable polymer and a second component of a monomer, each of which includes a functional group for reaction with an activated site on the substrate for grafting thereto and water. A method for grafting at least one of the components to a fiber, yarn or fabric substrate is also disclosed wherein increased flame retarding and yarn integrity is achieved while simultaneously allowing control of fabric porosity. This method does not significantly reduce fabric pliability as compared to uncoated fabric. Furthermore, the graft component may be selectively applied polymer to produce a preferred porosity range or a cutting pattern for the fabric substrate. A fabric, a portion of which includes a graft component or components thereon, forms another embodiment of the invention.

    Abstract: A method for making an air bag by forming a fabric structure of filaments or yarns in the configuration of an air bag, and grafting first and/or second components onto some or all of the filaments or yarns to provide the fabric structure with increased resistance to fraying, filament or yarn pull-out, or distortion during manufacture or use of the air bag compared to non-grafted filaments or yarns. The graft component(s) may be applied to the filaments or yarns prior to, during or after formation of the fabric structure. An air bag material suitable for use in a passive restraint system is also disclosed utilizing grafted fabric substrate provided by the above described method. A passive restraint system utilizing such fabrics is also described.
