COPOLYMER, PREPARATION THEREOF AND USE OF THIS COPOLYMER IN PREPARATION OF IONICALLY CONDUCTIVE MATERIAL

Japanese Patent JP3930575

B2

PURPOSE: To improve the conductivity and mechanical resistance of an ionically conductive material containing a solid polymer electrolyte, by allowing it to contain a specific crosslinkable copolymer.
CONSTITUTION: In the presence of a base such as a hydroxide of an alkali metal or the like, (A) an identical or different segments A, a portion of which is a solvating type while a portion of which is a nonsolvating type, each of which has a valence number i such that 1≤i≤6 and a weighted molar means of i of two or larger, which cannot be cross-linked by a radical crosslinking or by a Diels-Alder reaction and is bound to one or more segment B through a functional group Y which is an ether functional group or a secondary or tertiary amine functional group NR (wherein R is H, an alkyl, aryl or the like) having a carbon number of 30 or smaller, and (B) an identical or different segments B of the formula; Z(CH2)j (wherein Z is an organic group having a valence number j such that 1≤i≤6 and a weighted molar mean of j of two or larger, and contains one or more functional group which is crosslinkable by radical crosslinking or by a Diels-Alder reaction), which is bound to one or more segment A through the above-mentioned functional group Y, are allowed to undergo polycondensation.
