The above-mentioned resin sheet and molded article are characterized by generating heat when irradiated with microwaves.The present invention is directed to an electroconductive thermoplastic resin sheet which is prepared by first superposing an electroconductive nonwoven fabric mainly comprising electroconductive fibers and heat-meltable fibers upon one surface, both surfaces, or a part or all of the surface of a thermoplastic resin film as a base material layer, further superposing a thermoplastic resin film as a protective layer upon the nonwoven fabric so that they may come in contact with each other, heating and contact-bonding them at a temperature of the melting point or higher of the heat-meltable fibers. The present invention is also directed to an electroconductive thermoplastic resin-molded article which is prepared by heating the aforesaid electroconductive thermoplastic resin sheet up to a temperature at which the resin sheet softens, setting the resin sheet between a pair of female and male molds, the surface of at least one of which comprises a heat-resistant rubber, and then mating both the molds to mold the resin sheet.

摘要： A glycidyl ether of a phenolic compound of the formula: ##STR1## wherein each of R.sup.1 through R.sup.6 represents an alkyl group of from 1 to 6 carbon atoms; each of R.sup.7 to R.sup.12 represents a hydrogen atom, an alkyl group of from 1 to 4 carbon atoms, or an alkoxy group of from 1 to 4 carbon atoms; X represents a chlorine or bromine atom; GE represents a glycidyl ether group; a, b, c, d, and e are 0 or 1; and n is an average number of from 0.5 to 5. The high purity glycidyl ether of the phenolic compound can be produced by reacting the corresponding phenolic compound with an epichlorohydrin in an aprotic polar solvent in the presence of an alkali metal hydroxide and then treating the resulting crude glycidyl ether compound with an alkaline material in an organic solvent.
