    摘要: Polymer-clay nanocomposites and methods of making the same are provided. In an embodiment, a polymer-clay nanocomposite comprises a non-metal salt of an ionomer and a nanostructured layered clay. An example of the ionomer is a tetra-octyl ammonium salt of sulfonated polystyrene, and an example of the clay is sodium-montmorillonite.

    摘要: The present invention is directed to golf ball cover compositions containing blends of high or low carboxylic acid based copolymers and ethylene copolymers such as ethylene alkyl acrylates. The carboxylic acid groups of the blends are neutralized with metal cations. Golf balls produced with the cover molded thereon exhibit desired properties of distance and high coefficient of restitution without substantially sacrificing and/or improving characteristics like playability and durability when compared to existing covers comprising ionomeric resin blends.

    摘要: An electrosugrical unit for conducting a predetermined ionizable gas in a jet stream to the tissue at a predetermined flow rate sufficient to clear natural fluids from the tissue and to substantially expose the tissue stroma and for exposing the gas to an electrical radio frequency energy to ionize the gas in conductive pathways in the gas jet stream. The unit includes a nozzle which is releasably connected to a handle for easy manipulation by a surgeon with the nozzle including means for supporting an electrode in an optimal position for initiation of the ionization of the gas. Also, a connecting system is disclosed for connecting the hose on which the handle is mounted to a gas delivery apparatus and supply or electrical energy which permits the hose to rotate while maintaining a positive hermetic seal to prevent the hose from kinking during use by a surgeon.

    摘要: The present invention relates to polymeric compositions formed from sulfonated co- or terpolymers which are formed by a free radical co- or terpolymerization process, wherein the resultant co- or terpolymers have an Mn of about 5,000 to 200,000 and these co- or terpolymers have at least about 0.5 weight percent of chemically combined sulfur therein. The free radical co- or terpolymerization process of the instant invention can be generally described as a free radical emulsion polymerization of at least one conjugated diene or a mixture of styrene and butadiene with a sulfonate monomer which is water soluble, at a temperature sufficient to cause polymerization, wherein the initiator is preferably based on a peroxide initiator accelerated by a reducing agent, and suitable surfactants are employed. Upon completion of the free radical polymerization, the resultant latex is coagulated and the water insoluble polymer is recovered.
