Photoreactive monomer which has (i) at least one free-radically polymerizable C&#x2014;C double bond, (ii) at least one hydrophilic group selected from an ethylene glycol group and a polyethylene glycol group having at least 2 ethylene glycol units and (iii) at least one photoreactive group, the photoreactive group being a photoenolizable carbonyl group, and also a method for preparing the photoreactive monomers.

Photoreactive monomers

A description is given of a photoreactive polymer preparable by radical polymerization using at least one photoreactive monomer, where the photoreactive monomer has at least one radically polymerizable C&#x2014;C double bond, at least one hydrophilic group selected from an ethylene glycol group and polyethylene glycol groups having at least 2 ethylene glycol units, and at least one photoreactive group, the photoreactive group being a photoenolizable carbonyl group.

Photoreactive polymer

A new process is provided for preparing nitrile rubbers by free-radical polymerization in an organic solvent and in the presence of specific modifier substances. This polymerization may be followed by hydrogenation to give likewise new hydrogenated nitrile rubbers, the hydrogenation advantageously taking place likewise in organic solvent. The optionally hydrogenated nitrile rubbers obtained are notable for having fragments of the employed modifier substances in the main polymer chain and/or as end groups. They can be prepared with a wide diversity of molecular weights and polydispersity indices, especially with very low polydispersity indices.
