A polymer composite includes a functionalized polyisobutylene and an additional polyisobutylene-containing material. One or more methods of making the polymer composite are also provided. Where the functionalized polyisobutylene is applied to a polyisobutylene-containing material, the method of applying the functionalized polyisobutylene compound can be described as a modular method.

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 cured elastomer golf ball component is made by heating an elastomer compound containing an ethylenically unsaturated elastomer, an ethylenically unsaturated monomer, and first and second free radical initiators to a first crosslinking temperature T.sub.1 in a compression mold and partially crosslinking the elastomer, then heating to a second crosslinking temperature T.sub.2 and curing the elastomer component of the golf ball. Either: (i) the first initiator has a half-life of about 0.2-5 minutes at T.sub.1, the second initiator has a half-life of about 0.2-5 minutes at T.sub.2, and T.sub.2 is higher T.sub.1 by at least about 30° C.; or (ii) the second initiator's one-minute half-life temperature is at least about 30° C. higher than the first initiator's one-minute half-life temperature, T.sub.1 is within about 20° C. of the first initiator's one-minute half-life temperature, and T.sub.2 is within about 20° C. of the second initiator's one-minute half-life temperature.

There are provided a composition for encapsulation film, an encapsulation film, and an electronic device having the same. The present application may provide an encapsulation film having an excellent moisture barrier property, operability, workability, and durability and a structure including an element encapsulated by the encapsulation film.

Halogenated butyl rubbers are provided comprising lignins and co-reinforcing agents, where the ratio of the lignin to the co-reinforcing agent is selected so as to effectively modulate advantageous properties of the vulcanizate. The advantageous properties are achieved when using a ratio of lignin to the co-reinforcing agent, such as carbon black or silica, that is higher than in a reference vulcanizate, in effect the substitution of lignin for conventional reinforcing agents improves the reinforcement of the vulcanizates.

Provided is a structure having excellent flexibility represented by elastic restoring from compression or tensile elongation at break, and excellent lightness. A structure according to the present invention includes reinforced fibers, first plastic, and second plastic that exhibits rubber elasticity at room temperature, the reinforced fibers being discontinuous fibers, and the first plastic and/or the second plastic coating a crossing point between the reinforced fibers in contact with each other.

The present disclosure relates to an encapsulation composition, an encapsulation film comprising the same, an organic electronic device comprising the same, and a method for manufacturing an organic electronic device using the same, which provides an encapsulation composition capable of effectively blocking moisture or oxygen introduced into an organic electronic device from the outside and realizing an organic electronic device with an extremely small bezel part structure.

One embodiment of the present invention relates to a thermally conductive sheet containing graphite particles (A) including at least one selected from the group consisting of flake-like particles, ellipsoidal particles, and cylindrical particles, in which the graphite particles (A) are oriented in a thickness direction, and a thickness compression ratio is 24% or more at a temperature of 150° C. and a compressive stress of 0.14 MPa.

A shoe midsole composed of a foamed peroxide-crosslinked polyolefin elastomer includes a silane-grafted polyolefin component, an elastomeric component, and additives dispersed in the foamed peroxide-crosslinked polyolefin elastomer. The elastomer component includes one or more elastomeric polymers selected from the group consisting of ethylene vinyl acetate copolymer, polyolefin elastomers, olefin block copolymer, polyoctenamer, anhydride modified ethylene copolymers, ethylene propylene diene terpolymer, and combinations thereof. The silane-grafted polyolefin component and elastomer component are crosslinked with C—C bonds. Advantageously, the foamed peroxide-crosslinked polyolefin elastomer is substantially free of silane crosslinking as formed and substantially free of water. Characteristically, the additives and one or more elastomeric polymers are in sufficient amount that a melting temperature of crystalline regions in the foamed peroxide-crosslinked polyolefin elastomer is greater than 100° C. as measured by differential scanning calorimeter thermographs.
