A solid electrolyte membrane for solid polymer fuel cells, or the like is provided that is chemically stable in a strong acid atmosphere, and has low methanol cross-over as well as high proton conductivity. The solid electrolyte membrane is manufactured, using an electrolyte composition comprising a sulfonic acid group-containing polymer having a specific triazine structure. This polymer can be synthesized, for example, from a sulfonic acid group-containing dihydroxy compound having a triazine structure, and a difluoride.

The present specification discloses a toner for electrophotography.This toner comprises two or more kinds of binder resins, and is characterized in that the surface tension of each of the binder resins and the melt viscosity thereof, both at a temperature of 200.degree. C., are respectively below 30 dyne/cm and 100 poises or more, and the melt viscosity thereof and the storage modulus thereof, both at a temperature of 125.degree. C., are respectively below 5000 poises and below 40000 dyne/cm.sup.2, a toner comprising a surface tension reducing agent and a binder resin. Because the melt viscosity of the binder resin at a temperature of 200.degree. C. is 30 poises or more, a toner having an excellent void resistance can be obtained without a worsening of the fixability and blocking resistance thereof.

摘要:
In a process for preparing an ink for a drop-on-demand type ink jet printer, sonic vibration is applied to the ink which is being prepared or has been prepared so that a gas entrained into the ink by incorporation of a dye therein can be removed. This ink can be stably injected through a recording head, even if the size of the head is made smaller to increase the atomizing frequency, or the recording speed.

Flame retardation of 1,2-polybutadiene based upon the use of halogenated bisphenol bisacrylate reactive flame retardants, for example, 2,2-bis(4-methacryloyl-3,5-dibromophenyl)-propane. Flame retardancy performance of UL 94 V-0 or V-1 has been achieved without impairing desirable dielectric properties and heat resistance inherently possessed by 1,2-polybutadiene. If an aromatic bismaleimide modifier, for example, N,N'-4,4'-diphenylmethane bismaleimide, is jointly used, a thermal expansion coefficient less than a half of the thermal expansion coefficient of cured 1,2-polybutadiene can be achieved.
