Abstract
The invention is directed to compositions containing at least one olefinic monomer, at least one polymer prepared form an olefinic monomer, an indicator dye to the basic structure of which an olefinic polymerisable group is covalently bonded directly or via a bridge group, at least one diolefinic cross-linking agent, and an effective amount of a polymerisation initiator; to polymerisates of the compositions, the polymerisates being in the form of interpenetrating networks; to membranes and unsupported films prepared from the polymerisates; to carrier materials coated with the compositions and polymerisates; to optical sensors prepared from the polymerisates; and to methods of determining ions and/or gases in solutions and/or blood.

A composition, comprising:
- (a) at least one olefinic monomer (A),
- (b) at least one polymer prepared from at least one olefinic monomer,
- (c) an indicator dye to the basic structure of which an olefinic polymerisable group is covalently bonded directly or via a bridge group,
- (d) at least one diolefinic cross-linking agent;
- and
- (e) an effective amount of a polymerisation initiator, characterized in that upon polymerisation of the composition a polymerisate is prepared in the form of an interpenetrating network.
A transparent membrane, comprising:
- a polymerisate of
- (a) at least one olefinic monomer (A),
- (b) at least one polymer prepared from at least one olefinic monomer,
- (c) an indicator dye to the basic structure of which an olefinic polymerisable group is covalently bonded directly or via a bridge group,
- (d) at least one diolefinic cross-linking agent;
