Paragraph 0047-0048; 0052, (2020/08/17)
According to the invention, the safety of the battery can be improved based on introduction of phosphate into the gel polymer electrolyte, , the adjustable flexibility is improved by introduction of aPEO chain segment, and the stability and the polymerization capability are improved by introduction of acrylate; thus, further research is carried out on the basis of the prior art, the polyfunctional phosphate cross-linking agent is obtained and is applied to the preparation of the phosphate-based cross-linked gel polymer electrolyte, so the cross linking agent can be copolymerized with other functional monomers to synthesize gel polymer electrolyte; the gel polymer electrolyte has the advantages of simple and convenient preparation method, high ionic conductivity, high thermal stability andgood electrochemical stability, the assembled sodium ion battery has good cycling stability and high-temperature performance, and the phosphate-based gel polymer electrolyte with high safety is provided for quasi-solid sodium/lithium ion batteries.

PROCESSES FOR PRODUCING HYDROXYALKYL (METH)ACRYLATE

Page/Page column 24--27; 34-37, (2008/06/13)
Processes for producing a hydroxyalkyl (meth)acrylate which comprise reacting (meth)acrylic acid with an alkylene oxide in the presence of a catalyst. A first process is characterized in that the amount of the acid ingredient is kept, on calculation, at 0.010 or more in terms of molar ratio to the catalyst present in the liquid reaction mixture and that the liquid reaction mixture from which the hydroxyalkyl (meth)acrylate has been distilled off is used in the subsequent reaction. A second process is characterized in that a dialkylene glycol mono(meth)acrylate is supplied to the reaction system to cause the dialkylene glycol mono(meth)acrylate to coexist in the liquid reaction mixture.
