  • Patent number: 9416447
    Abstract: Block copolymers (BCPs) and synthetic infiltration synthesis (SIS) are used to double the line density on a substrate. The BCP comprises first and second interconnected BCP components with a functional group at the junction or interface of the components. After deposition of the BCP on the substrate and annealing, a pattern of parallel stripes of first and second BCP components is formed with a pattern of functional group interfaces between the components. Each of the BCP components is non-reactive with atomic layer deposition (ALD) precursors, while the functional group is reactive with the ALD precursors. The ALD results in the infiltration of inorganic material into the interfaces where the reactive functional groups are located but without affecting the BCP components. After removal of the organic material, a pattern of parallel lines of inorganic material remains with a pitch half that of the stripes of BCP components.

  • Publication number: 20100137523
    Abstract: Creation of nanoparticle structures in two and three dimensions is advantageous in providing a number of functions such as in relation to catalytic, optical, electronic and magnetic propertied and other actions. Fabrication of such structures poses a considerable technical challenge. A block copolymer pair is used as a matrix to spatially organizes and aligns loaded inorganic materials in the form of nanoparticles. The inorganic precursors are selectively incorporated to a specific block of a di or tri block copolymer so that through solvent evaporation, reduction and mechanical working such as LAOS the orientation and positioning of the block copolymers nanoparticles are obtained into a desired structure.

  • Publication number: 20100056303
    Abstract: The invention provides a golf ball material composed of an ionomeric resin composition obtained by melt-blending under applied heat one or more compounds selected from among UV/EB-curable materials with, in the presence of a peroxide, a non-ionomeric thermoplastic resin and an ionomeric resin; or of an ionomeric resin composition obtained by using, instead of the ionomeric resin, an acid-containing polymer base of the ionomeric resin and subjecting the acid-containing polymer composition similarly prepared by melt-blending under applied heat to an acid-neutralizing reaction with a metal ionic species. Methods for preparing such a material, and golf balls which include as a component therein a molding made of the golf ball material are also provided. The golf ball material has a good thermal stability, flow and processability, and can thus be used to obtain high-performance golf balls endowed with an excellent abrasion resistance, scuff resistance, durability and flexibility without a loss of rebound.

    Abstract: The present invention provides a catalyst, which has enough catalytic activity as a transition metal particle catalyst including platinum family and the like, is easily separable from products, is reusable and is easily prepared. To prepare the transition metal cluster catalyst of the present invention, an insoluble complex is prepared by forming a complex between a polymer with nitrogen-containing group, such as pyridinium and ammonium group in the principal chain, and a later transition metal compound; and then reducing the complex with a reductant. The transition metal forms clusters, which are stabilized by the polymers. Namely, the present invention is a transition metal cluster catalyst, wherein transition metal clusters are supported by a polymer, which is obtained by reduction reaction of a complex of a transition metal and a polymer with nitrogen-containing group.

The initiator comprises at least one metal salt and a free radical generating component. The metal salt of the composition is chosen so that it is reduced at the surface, where the standard reduction potential of the metal salt is greater than the standard reduction potential of the surface, and where when the composition is placed in contact with the surface, the metal salt is reduced at the surface, and interacts with the free radical generating component, thereby initiating cure of the radically curable component of the composition. No catalytic component is required in the composition for efficient curing.
