A shoe midsole composed of a foamed peroxide-crosslinked polyolefin elastomer includes a silane-grafted polyolefin component and an elastomer component. The elastomer component includes ethylene vinyl acetate copolymer and a component selected from the group consisting of polyolefin elastomers, anhydride modified ethylene copolymers, and combinations thereof. The silane-grafted polyolefin component is crosslinked to the elastomer component with C-C bonds. The foamed peroxide-crosslinked polyolefin elastomer includes a plurality of closed cells. Characteristically, the foamed peroxide-crosslinked polyolefin elastomer is substantially free of silane crosslinking as formed and substantially free of water.

A slidable rubber material that has an amino-modified interfacial layer that does not affect the compression set. Although the slidable rubber material includes a rubber component such as a butyl rubber or halogenated butyl rubber etc. having the low-compression set, which contains a vulcanization agent such as a nitrogen/sulfur compound or a vulcanizing auxiliary agent, the rubber part is coated with a silicone rubber layer. The slidable rubber material exhibits a slidability and resists the detachment or elution of fine particles from the coating layer. A rubber component and a vulcanization agent; an interfacial modification layer that coats the rubber part and an amino-modified silicone compound is incorporated with surface molecules of the rubber part; and a layer that coats the interfacial modification and contains solid fine particles, an addition-type or condensation-type silicone rubber in which the particles are dispersed, and a curing catalyst for silicone rubber.

A process for producing a crosslinked polymer involves contacting an epoxidized unsaturated isoolefin copolymer with a catalytic amount of an acid in an absence of a solvent. A process for producing a hydroxylated unsaturated isoolefin copolymer involves contacting an epoxidized unsaturated isoolefin copolymer with a catalytic amount of an acid in an absence of a solvent. A hydroxylated unsaturated isoolefin copolymer having hydroxyl groups in endo configurations may be produced thereby.

A silicone rubber composition is provided. The silicone rubber composition comprises a hydrophobic silica, polyamide microparticles, a liquid organopolysiloxane having two chain ends each bearing an alkenyl group, a liquid polyhydroalkylsiloxane having two chain ends each bearing an SiR′.sub.3O.sub.1/2 group, and a hydrosilylation catalyst. The ratio of the number of (R′HSiO.sub.2/2) units in the polyhydroalkylsiloxane to the number of alkenyl groups is greater than 5. Such a composition has good adhesive properties with respect to a crosslinked butyl rubber composition, good friction resistance properties and good flexibility properties.

A non-crosslinked rubber laminate which is a rubber laminate includes a butyl rubber-containing layer stacked with an ethylene propylene diene rubber and/or ethylene propylene rubber-containing layer, wherein such non-crosslinked rubber laminate is characterized in that the ethylene propylene diene rubber and/or ethylene propylene rubber-containing layer is a rubber-containing layer that contains a low-molecular-weight polyolefin, a phenolic resin, and a crosslinking agent, where: the low-molecular-weight polyolefin is contained by 40 to 70 parts by weight, the phenolic resin is contained by 1 to 4 parts by weight, and the crosslinking agent is contained by at least 1 part by weight, relative to the ethylene propylene diene rubber and/or ethylene propylene rubber constituting a total of 100 parts by weight. An air conditioning hose made of the rubber laminate, for example, can accommodate POE-based lubricating oils and retain vibration absorption characteristics.

Provided is a thermoplastic resin composition for refrigerant transporting piping having high barrier properties, flexibility, and good extrusion processability. The thermoplastic resin composition for refrigerant transporting piping is composed of: a matrix containing a thermoplastic resin; and a domain containing a rubber dispersed in the matrix, and is characterized in that the thermoplastic resin has a melting point of 150° C. or higher, the rubber is a butyl-based rubber or an olefin-based rubber, the matrix contains a viscosity stabilizer, the thermoplastic resin composition contains a processing aid and at least one selected from the group consisting of a phenylenediamine-based anti-aging agent, a quinoline-based anti-aging agent, and a trihydric alcohol having a triazine skeleton, and at least a portion of the rubber is crosslinked.

The current invention concerns a method for preparing an emulsion comprising the steps: mixing a first phase and a second phase in a layer multiplier to produce a multilayered fluid structure, and collapsing said multilayered fluid structure, thereby dispersing the second phase in the first phase creating an emulsion. The current invention relates to a method for producing dispersions. The current invention also concerns the emulsions produced by said method. The current method also relates to polymer emulsions, particularly polyisobutene emulsions with a high content of polyisobutene.

A substrate subject to degradation at temperatures above 100° C. is coated with a nanostructured ceramic coating having a thickness in excess of 100 nm, formed on a surface of the substrate, wherein a process temperature for deposition of the nanostructured coating does not exceed 90° C. The coating may be photocatalytic, photovoltaic, or piezoelectric. The coating, when moistened and exposed to ultraviolet light or sunlight, advantageously generates free radicals, which may be biocidal, deodorizing, or assist in degradation of surface deposits on the substrate after use. The substrate may be biological or organic, and may have a metallic or conductive intermediate layer.

The invention relates to a method to reduce or prevent agglomeration of polyisobutylene particles in aqueous media by LCST compounds and highly pure isobutylenes obtained thereby. The invention further relates to polyisobutylene products comprising the same or derived therefrom.

A cured elastomer comprising: an elastomer at 100 parts per hundred rubber (phr); and an expandable thermoplastic microsphere at about 0.1 to about 10 phr. Such a cured elastomer can be used, optionally with additives, in an air barrier article that is selected from the group consisting of a tire innerliner, a pneumatic tire, a tire curing bladder, an air sleeves, a diaphragm, and a hose. With microspheres the compounded cured elastomer shows a reduction in specific gravity and a reduction in permeability. Both of these properties are highly desirable in tire design and performance.
