Polymerizable monomer

A polymerizable monomer, comprising:

• exactly one phosphorus atom;
• wherein an oxygen atom having a double bond is present on the phosphorus atom;
• wherein two or three identical amino acids are each bound to the phosphorus atom via one NH group;
• wherein, in the case of two identical amino acids, one R1 residue is bound to the remaining binding site of the phosphorus atom;
• wherein each amino acid has an amino acid residue adjacent to the NH group;
• and
• wherein the hydroxy group of the carboxy group of the amino acid is replaced by X—R3, wherein R3 is another residue;
• wherein X is selected from O, NH, S, and CH2;
• wherein the R3 residue comprises a polymerizable group;
• and
• wherein several of the polymerizable monomers are directly polymerizable with one another via these polymerizable groups or are polymerizable with a second type of monomers via these polymerizable groups to form copolymers.
