Title:
HYDROPHILIC POLYMER, PRODUCTION METHOD FOR SAME, BINDER, ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2015/122498
Kind Code:
A1
Abstract:
Provided are a hydrophilic polymer that has superior hydrophilicity, flexibility, and adhesiveness with a metal, a production method for the same, an electrode containing the same, and a negative electrode for a lithium ion secondary cell. The hydrophilic polymer is expressed by formula (1), within which the structure of formula (2) accounts for 10-99 mass%, and the ratio (B/A) of the molar number (B) of imide units of formula (2) relative to the molar number (A) of urethane units of formula (3) is 1-30 (R1: a divalent organic group having 4-30 carbon atoms; R2: a divalent organic group containing a polyoxyalkylene structure having 2-5 carbon atoms, a straight chain or branched shape, and a number average molecular weight of 100-10,000; R3: a trivalent or more organic group containing one or two aromatic rings having 4-30 carbon atoms; R4: a tetravalent organic group having 4-30 carbon atoms; X: a carboxyl group or a sulfonic acid group; x: 1-800; y: 1-800; z: 1-100; a:1-4; when X is a carboxyl group, the number of aromatic rings in R3 is 1, and a is 1).
