Abstract: A triphenylene derivative represented by the following formula (I): wherein R1-R6 independently denote an ethoxy or propoxy group-containing segment having at least two ether oxygen atoms and a terminal group comprising a linear or branched alkyl group having 1-20 carbon atoms, said alkyl group including at least one hydrogen atom optionally substituted with fluorine atom and at least one methylene group optionally substituted with —O—, —CO—, —CH═CH—, —C≡C— or epoxy group. The triphenylene derivative is usable as an ion-transporting compound of a component for an electrolyte of, e.g., secondary battery since the triphenylene derivative has an ionic conductivity anisotropy due to its columnar structure in discotic liquid crystal phase.

Abstract: Disclosed is a novel compound having activity as an ionophore for ion transport, which is a monoester or monoamide of 1,3,5-trimethyl-1,3,5-cyclohexane tricarboxylic acid, i.e. Kemp's triacid or the stereoisomer thereof, the group R in the ester group --COOR or in the amide group --CONHR being an aralkyl group or aryloxyalkyl group having 7 to 20 carbon atoms. The monoester and monoamide derivatives can be synthesized from anhydride of Kemp's triacid by subjecting the anhydride to a ring-opening esterification or amidation reaction with an alcohol or amine. On the other hand, both of the stereoisomers can be obtained by the dehydrohalogenation reaction of 1,3,5-trimethyl-1,3,5-cyclohexane tricarboxylic acid anhydride acid halide with an alcohol or amine followed by the ring-opening hydrolysis reaction on the anhydride group.

Abstract: Disclosed is a thermoplastic polyurethane resin composition which contains a thermoplastic polyurethane resin (A) and a modified polyolefin resin (B) as its components. The polyurethane resin shows excellent flexibility, smooth touch, and stretching property when molded in the form of films or sheets. It is quite suitable for excretion-treating materials such as a diaper.

Abstract: A diamine derivative expressed by the following general formula (I): ##STR1## wherein R.sup.1 and R.sup.2 stand, independently from each other, for a hydrogen atom, an alkyl group, an aralkyl group or an aryl group. The diamide derivative is useful as an ionophore which can selectively transport cupric ions through liquid membranes.
