Abstract
A polymeric polyol such as polyglycidol derivative wherein at least 10% of the ends of molecular chains are capped with monovalent groups, typically cyano-substituted monovalent hydrocarbon groups has a high ionic conductivity, remains amorphous even when an ion-conductive salt is dissolved in high concentrations, and is suitable as a polymer electrolyte.

A polymeric compound comprising a unit of the formula
- —CH2CH(CH2OH)O— and a unit of the formula —CH2CH(OH)CH2O— wherein at least 50% of the terminal hydroxyl groups of molecular chains are capped with monovalent groups of at least one type selected from the group consisting of
- halogen atoms,
- cyano-substituted monovalent hydrocarbon groups, R1CO— groups wherein R1 is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 10 carbon atoms and selected from the group consisting of alkyl, aryl, aralkyl, and groups in which some or all of the hydrogen atoms of the alkyl, aryl, and aralkyl are substituted with a halogen, cyano, hydroxyl, amino, aminoalkyl, or posphono group,
- R13Si— groups wherein R1 is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 10 carbon atoms and selected from the group consisting of alkyl, aryl, aralkyl, and groups in which some or all of the hydrogen atoms of the alkyl, aryl, and aralkyl are substituted with a halogen, cyano, hydroxyl, amino, aminoalkyl, or posphono group,
- amino groups, and
- alkylamino groups.
A polymeric compound comprising a unit of the formula —CH2CH(CH2OH)O— and a unit of the formula —CH2CH(OH)CH2O— wherein at least 50% of the terminal hydroxyl groups of molecular chains are capped with cyanoethyl, a mixture of cyanoethyl and trimethylsilyl, acetyl, or cyanobenzoyl.
