SOLVENT-FREE PHASE-INVERSION EMULSIFICATION PROCESS FOR PRODUCING AMORPHOUS POLYESTER RESIN EMULSIONS
An organic solvent-free phase-inversion emulsification process for a low molecular weight amorphous polyester resin includes forming a mixture by adding to the amorphous polyester resin: i. a surfactant; ii. an aqueous solution of a neutralizing agent; and iii. a portion of water that is about 40% or less of a total amount of water used to form a phase-inversion emulsion, heating the mixture to dissolve the amorphous polyester resin to provide a dissolved amorphous polyester and adding water up to the total amount of water to the dissolved amorphous polyester to form a latex of the amorphous polyester resin. The resultant latex is used in processes of making a toner composition. A latex of an amorphous polyester resins is made by such processes have latex particles that are unimodal.
Release film, laminate and method for manufacturing same, and method for manufacturing fuel cell
A release layer of a release film for producing a membrane electrode assembly of a polymer electrolyte fuel cell comprises a cyclic olefin polymer comprising an olefin unit having a C.sub.3-10alkyl group as a side chain thereof. The release layer may have a glass transition temperature of about 210 to 350 C. The release layer may have a transition point of a dynamic storage modulus E in a range from 50 to 100 C. An ion exchange layer comprising an ion exchange polymer may be laminated on the release layer of the release film by a roll-to-roll processing to produce a laminate. The release film may be separated from the laminate to give the membrane electrode assembly. The release film achieves improved production of a membrane electrode assembly (an electrolyte membrane and/or an electrode membrane) of a polymer electrolyte fuel cell.
