International Classification:

C08K 3/34

US Classification:

524445, 524492, 524493, 524495

Abstract:

This invention relates to preparation of nanocomposites comprised of elastomer and a dispersion of an at least partially exfoliated water swellable clay and to rubber compositions containing such nanocomposite and articles of manufacture which contain at least one component thereof. The nanocomposite is prepared by addition of a water suspension of water swellable clay particles to an anionic aqueous emulsion of elastomer particles to form a mixture to which an amine having at least two amine centers is added to intercalate and at least partially exfoliate the water swelled clay particles by an ion exchange within the galleries of the multilayered clay with cation exchangeable ion(s) and to aid in coagulating the elastomer and resultant clay particles to form said nanocomposite.

Abstract:

Pneumatic rubber tire having at least one component of a polybutadiene-rich rubber composition comprised of a blend of a continuous phase of a specialized cis 1,4-polybutadiene rubber and a dispersed phase comprised of a composite of styrene/butadiene elastomer which contains a dispersion of at least partially exfoliated, intercalated, clay platelets, wherein said cis 1,4-polybutadiene rubber and styrene/butadiene elastomer have spatially defined glass transition temperatures, wherein said blend contains amorphous silica and carbon black reinforcement. Such tire component may be, for example, a circumferential tread having a running surface intended to be ground-contacting or a sidewall insert.

Abstract:

Two and three dimensional polynucleic acid structures, such as periodic lattices, may be constructed from an ordered array of antiparallel double crossover molecules assembled from single stranded oligonucleotides or polynucleotides. These antiparallel double crossover molecules have the structural rigidity necessary to serve as building block components for two and three dimensional structures having the high translational symmetry associated with crystals.

Abstract:

The subject invention is directed towards tire components which are comprised of rubber compositions which are comprised of (1) about 2 phr to about 45 phr of a trans-1,4-isoprene-butadiene copolymer which has about 4 weight percent to about 16 weight percent butadiene repeat units and from about 84 weight percent to about 96 weight percent isoprene repeat units, wherein the trans-1,4-isoprene-butadiene copolymer has a Mooney ML 1+4 viscosity which is within the range of about 35 to about 80; and (2) about 55 phr to about 98 phr of at least one other elastomer, preferably a diene based elastomer. The most preferred tire components are those which contain cord reinforcements and require adequate green strength to enhance the tire building and shaping process to maintain cord integrity in the final cured tire.
