摘要:
Disclosed is a triazine ring-containing hyperbranched polymer containing a repeating unit structure represented by the expression (1). By this means, it is possible to achieve a triazine ring-containing polymer which, alone, has high heat resistance, high transparency, high refractive index, high light resistance, high solubility, low volume shrinkage without adding metal oxides; and also a membrane-forming composition containing the same. In the formula, R and R′ represent independently a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and A represents an alkylene group optionally having a branched or alicyclic structure of 1 to 20 carbon atoms.

摘要:
A Drain wire led out from the interior to the exterior of a shielded wire is covered with a heat shrinkable tube made of an insulating resin or with a rubber tube including silicon or EPDM (ethylene-propylene rubber). A water-stop agent is penetrated between the element wires of the drain wire in the heat shrinkable tube or the rubber tube. In addition, A boundary portion between a terminal connected to an end of the drain wire and the heat shrinkable tube is covered with a rubber stopper.
摘要:
Chemically modified carbon nanotubes composed of carbon nanotubes (such as multiwall carbon nanotubes) having carboxyl groups on the surface thereof and polymeric aniline (such as 3- to 300-meric aniline) bonding thereto through the amide linkage. The chemically modified carbon nanotubes exhibit good affinity with organic solvents and readily disperse into organic solvents.
