POLYSILOXANE COMPOUND AND SOLID POLYMER ELECTROLYTIC COMPOSITION USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polysiloxane compound in which a polyalkylene oxide group and an acrylic group are introduced as a side chain to a normal chain of a methyl siloxane polymer at the same time.

SOLUTION: This invention relates to the polysiloxane compound and a solid polymer electrolytic composition using it, for more detail it relates to the polysiloxane compound in which the polyalkylene oxide group and the acryl group are introduced as the side chain to the normal chain of the methyl siloxane polymer so that a crosslinking is easy and which can adjust the degree of crosslinking by the concentration of the above acryloyl group, and to the solid polymer electrolytic composition in which ionic conductance and electrochemical stability at ordinary temperature are improved by the use of the above polysiloxane compound as a crosslinking agent and which can be not only used as an electrolyte thin film and a polymer electrolyte of a small size and high-capacity lithium-polymer secondary battery and the like but also can adjust mechanical properties of an electrolyte easily by the adjustment of the degree of crosslinking of the above polysiloxane compound.
