GRAFT COPOLYMER, PROCESS FOR MANUFACTURING GRAFT COPOLYMER, AND PROCESS FOR PREPARING GEL-LIKE POLYMER ELECTROLYTE CONTAINING GRAFT COPOLYMER AND INTERMEDIATE COPOLYMER OF GRAFT COPOLYMER

摘要

PROBLEM TO BE SOLVED: To provide a novel graft copolymer useful as a binding agent of a lithium battery electrode, a process for manufacturing the graft copolymer and a process for preparing a gel-like polymer electrolyte containing the graft copolymer and an intermediate copolymer of the graft copolymer.SOLUTION: There is provided a graft copolymer containing a skeleton polymer represented by the formula (I), where A, B, R, R, R, R, R, R, G, G, G, G, Y, Yand k are as defined in the application, and a branched polymer. There are also disclosed a process for manufacturing the graft copolymer and a process for preparing a gel-like polymer electrolyte containing the graft copolymer and an intermediate copolymer of the graft copolymer.SELECTED DRAWING: Figure 10
