Claims
- 1. An ion-selective electrode comprising a body wherein said body is formed from a member selected from the group of conductors and semiconductors and a membrane separating the body from a solution to be measured, said membrane consisting essentially of a crosslinked polymer material prepared by
- (a) polymerizing a mixture comprised of allyloxy-substituted propylene glycol telomer and calcium bisdiallyl phosphate;
- (b) removing ions from the polymerized material by equilibration with a solution of 10.sup.-3 molarity with respect to the ions to be removed said ions of the type to be selected by said electrode, to leave gaps conforming to said ions to be selected.
- 2. A procedure for manufacturing an ion-selective electrode, said procedure comprising forming a membrane on a body formed from a member of the group of conductors and semiconductors to separate the body from a solution to be measured by
- (a) polymerizing a mixture comprised of allyloxy-substituted propylene glycol telomer and calcium bisdiallyl phosphate with the aid of heat or ultraviolet light;
- (b) removing ions of the type to be selected by said electrode from the polymerized material by equilibration with a solution of 10.sup.-3 molarity with regard to the ions to be removed.
