Abstract

Abstract An ionically conductive materiaz comprises crosslinked copolymer prepared by the reaction of (A) organopolysiloxane and polyoxyalkylene copolymer, which has at least 2 silicon-bonded hydrogen atoms in each molecule, with (B) polyoxyalkylene having at least 2 aliphatically unsaturated hydrocarbon groups in each molecule, and (C) metal ion from Group I or Group II of the Periodic Table, wherein said metal ion is dispersed in said crosslinked copolymer. Component (B) is a polyoxyalkylene having an aliphatically unsaturated hydrocarbon group at both chain terminals or a mixture of molecules in which some have an aliphatically unsaturated hydrocarbon group at both ends and some having the group at only one end. This mixture gives the highest conductivity.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 66 words
Ionically conductive material which comprises crosslinked copolymer prepared by the reaction of (A) organopolysiloxane and polyoxyalkylene copolymer which has at least 2 silicon-bonded hydrogen atoms in each molecule with (B) polyoxyalkylene having at least 2 aliphatically unsaturated hydrocarbon groups in each molecule, and (C) metal ion from Group I or Group II of the Periodic Table, wherein said metal ion is dispersed in said crosslinked copolymer.
Claim 2
Dependent Claim 66 words
Ionically conductive material which comprises crosslinked copolymer prepared by the reaction of (A) organopolysiloxane and polyoxyalkylene copolymer which has at least 2 silicon-bonded hydrogen atoms in each molecule with (B) polyoxyalkylene having at least 2 aliphatically unsaturated hydrocarbon groups in each molecule, and (C) metal ion from Group I or Group II of the Periodic Table, wherein said metal ion is dispersed in said crosslinked copolymer.
Claim 3
Dependent Claim 134 words
Method for the preparation of ionically conductive material having the characteristic that a mixture of (A) organopolysiloxane and polyoxyalkylene copolymer having at least 2 silicon-bonded hydrogen atoms in each molecule, (B) polyoxyalkylene having at least two aliphatically unsaturated hydrocarbon groups in each molecule, in a quantity which affords a value of ( 1:5 ) to ( 10:1 ) for the ratio between the number of moles of aliphatically unsaturated hydrocarbon groups in the present component and the number of moles of silicon-bonded hydrogen atoms in component (A), and (C) the salt of a metal from Group I or Group II of the Periodic Table, at 0.5 to 20 weight parts per 100 weight parts of the total quantity of component (A) plus component (B), is cured in the presence of (D) hydrosilylation reaction catalyst.
Claim 4
Dependent Claim 134 words
Method for the preparation of ionically conductive material having the characteristic that a mixture of (A) organopolysiloxane and polyoxyalkylene copolymer having at least 2 silicon-bonded hydrogen atoms in each molecule, (B) polyoxyalkylene having at least two aliphatically unsaturated hydrocarbon groups in each molecule, in a quantity which affords a value of ( 1:5 ) to ( 10:1 ) for the ratio between the number of moles of aliphatically unsaturated hydrocarbon groups in the present component and the number of moles of silicon-bonded hydrogen atoms in component (A), and (C) the salt of a metal from Group I or Group II of the Periodic Table, at 0.5 to 20 weight parts per 100 weight parts of the total quantity of component (A) plus component (B), is cured in the presence of (D) hydrosilylation reaction catalyst.
