Provided are an electroconductive composition capable of affording a conductor having excellent stretchability and excellent electrical resistance stability; a conductor obtained from the electroconductive composition; and a flexible printed wiring board including a patterned conductor formed using the electroconductive composition. It is an electroconductive composition or the like containing: at least one selected from a block copolymer and a functional group-containing elastomer; and a chain-like silver powder in the form of aggregate particles into which microparticles have aggregated, in which the chain-like silver powder has a tap density of 2.0 g/cm 3 or less. The block copolymer is preferably a block copolymer represented by the below-mentioned formula (I):
X 1 -Y-X 2 (I)
(wherein, X 1 and X 2 independently represent a polymer unit having a glass transition point Tg of 0°C or more; and Y represents a polymer unit having a glass transition point Tg of less than 0°C).

摘要:
A thermoplastic elastomer compound is disclosed having a high strain recovery rate and a high strain fixity rate to provide shape memory, preferably manageable shape memory. The thermoplastic elastomer compound comprises styrene-ethylene/butylene-styrene and a paraffin wax having less than about 0.5% oil content. Shape modes of articles made from the thermoplastic elastomer compound can be altered by at least one thermo-mechanical event to cause deformation of the compound from a first shape to a second shape with retention of the compound in the second shape for any reasonable time interval.

Methods and compositions are provided for preparation of thermoplastic gels. The compositions have a base composition including a thermoplastic gel and a softener oil and the gel has a hardness between 15 Shore 000 and 65 Shore 000. The gel may also include an additive, such as a mineral filler, an anti-tack agent, and a mixture of a mineral filler and an anti-tack agent. The softener oil may be a high molecular weight oil having a molecular weight greater than about 250 g/mol.

Provided is a method of manufacturing a patterned substrate. The method may be applied to a process of manufacturing a device such as an electronic device or integrated circuit, or another use, for example, to manufacture an integrated optical system, a guidance and detection pattern of a magnetic domain memory, a flat panel display, a LCD, a thin film magnetic head or an organic light emitting diode, and used to construct a pattern on a surface to be used to manufacture a discrete tract medium such as an integrated circuit, a bit-patterned medium and/or a magnetic storage device such as a hard drive.

摘要:
The present invention is a pneumatic tire comprising an inner liner disposed on the inner side of the tire. The inner liner is composed of a sheet made of an elastomer composition containing a styrene-isobutylene-styrene triblock copolymer by more than or equal to 7 percent by mass and less than or equal to 93 percent by mass and an isobutylene-based modified copolymer containing a ²-pinene component by more than or equal to 7 percent by mass and less than or equal to 93 percent by mass. In the inner liner, a ratio Gs/Gb between an average thickness Gb in a bead region Rb extending from a tire largest width position to a bead toe and an average thickness Gs in a buttress region Rs extending from the tire largest width position to a corresponding position Lu at a belt layer end is 0.30 to 0.75.
