Add rear mixed liquor the reaction was continued at 40~60 DEG C 2~3h, then raises temperature to 70~90 DEG C of reactions until C=C disappears, reaction terminates
Organic solvent is removed, product C is obtained;
2) it is sufficiently mixed product C and organic solvent to obtain solution D, 45~60 DEG C is preheated in inert gas environment, it will
1,3- propyl sultone is added in solution D, is reacted 16~20 hours at 45~60 DEG C, removes organic solvent and obtains product E, product
E is formula (1) structure.
Preferably, DMAA and molar ratio≤0.04 PEO in the step 1);Organic solvent described in step 1) is

The room temperature electrochemical window is stablized in 5V or more.
Contain amphoteric ion full solid state polymer electrolyte film answering in lithium ion battery the invention also discloses described
With.
The present invention grafts to PEO on the side chain of PMHS, to reduce glass transition temperature, to reduce solid polymer
The crystallinity of electrolyte, since the electric action of PEO is only happened at noncrystalline domain, conductance can be improved by reducing crystallinity
Rate, simultaneously because PMHS main chains are softer, motility is strong, can reinforce the sub-chain motion ability of PEO, play and further increase
The effect of conductivity.In PMHS side chain graft amphoteric ions, can play the role of further increasing conductivity, the reason is that both sexes
Ion (sulfobetaines) can promote electron delocalization, while sulfonic acid group is easily by the attack of electrophilic group, it is easier to it is low
The Li of cloud density+It interacts, plays and promote lithium salts dissociation, form new lithium ion mobility channel, reach into one
Step improves the effect of conductivity;On the other hand, due to introducing amphoteric ion, increase the interface stability of electrolyte with it is compatible
Property, so that polymer electrolyte electrochemical window is improved.
Compared with prior art, the invention has the advantages that:1, the vitrifying of polymer dielectric is reduced
Transition temperature, to reduce crystallinity;2, electrolyte leakage and the safety decomposed existing for liquid electrolyte can be solved to ask
Topic;3, room-temperature conductivity reaches 3.39 × 10-4S·cm-1, decomposition voltage is more than 5V, basically reaches commercially use demand;4,
