摘要:
The invention provides a process for readily preparing polymeric solid electrolyte, i.e., ion conductive polymer having excellent properties.The process of the invention comprises steps of subjecting at least one of the following component A and component B to contain an alkali metal salt and/or an ammonium salt and mixing the components A and the component B.Component A: a solution obtained by dissolving a radical polymerization promotor in a specific polyether base macromonomer.Component B: a solution obtained by dissolving a radical polymerization initiator in a specific polyether base oligomer and/or an organic non-aqueous solvent.To at least one of the component A and component B, a radical polymerization retarder is added, if desired.The process of the invention can be carried out by a simple step comprised of mixing the two components at room temperature and provides the solid polyelectrolyte having a high inonic conductivity.The high-ion-conductive solid polyelectrolyte prepared by the process of the invention is very useful as a raw material for lithium cells, plastic cells, large capacity electrostatic capacitors, electrochromic displays and other overall solidificated systems.

A method for producing a cross-linked polyvinyl alcohol separator having a film of cross-linked polyvinyl alcohol for an alkali-zinc secondary battery, and a cross-linked polyvinyl alcohol separator produced by the method are disclosed. The method includes the steps of:(1) providing a film of polyvinyl alcohol having degree of saponification of 70 to 98.5% and containing 1,2-diol units;(2) contacting the film of polyvinyl alcohol with an oxidizing agent to effect oxidative cleavage of the 1,2-diol units;(3) contacting the film of polyvinyl alcohol with an acid catalyst to catalyze acetalization to form a film of cross-linked polyvinyl alcohol; and(4) preparing a separator with the film of cross-linked polyvinyl alcohol.
