A multi-armed core is provided by any of a number of possible routes, exemplary preferred routes being living anionic polymerization that is initiated by a reactive, functionalized anionic initiator and ?-caprolactone polymerization of a bis-MPA dendrimer. The multi-armed core is preferably functionalized on some or all arms. A coupling reaction is then employed to bond surface decoration to one or more arms of the multi-armed core. The surface decoration is a small molecule or oligomer with a degree of polymerization less than 50, a preferred decoration being a PEG oligomer with degree of polymerization between 2 and 24. The nanoparticles (particle size?10 nm) are employed as sacrificial templating porogens to form porous dielectrics. The porogens are mixed with matrix precursors (e.g., methyl silsesquioxane resin), the matrix vitrifies, and the porogens are removed via burnout.

  • Patent number: 7723434
    Abstract: An olefinic thermoplastic elastomer with improved properties can be obtained by melting and kneading a graft copolymer, acrylic rubber, a crosslinking agent, and a co-crosslinking agent. The graft copolymer is composed of an olefin polymer segment formed from a nonpolar ?-olefin monomer and a vinyl polymer segment formed from a vinyl monomer, with particles of one segment being dispersed in the other segment. The particle diameter is 0.01 to 1 ?m. The acrylic rubber can be obtained by polymerizing a monomer mixture containing methoxyethyl acrylate.

  • Patent number: 7642325
    Abstract: A non-sticky water-based coating material in the form of a film applied to the face of a circuit board that is loaded with electronic parts; which comes into contact with the outside environment. The coating material can be formed into the film at room temperature without using a coalescence, does not contain a solvent and forms a membrane having flexibility, low Young's modulus, favorable adhesive properties, moisture resistance and insulating properties. Specifically, the non-sticky water-based conformal coating material includes a resin wherein a flexible acrylic resin having glass transition temperature of at most 0° C. is the main chain and a vinyl polymer having a glass transition temperature of at least 20° C. is grafted to the flexible acrylic resin; the content of the vinyl polymer being 10 to 70% by weight based on the flexible acrylic resin.
