<p>A process for the treatment of archival material, more especially entire books and other bound volumes, to improve the paper structure and provide some protection against degradation, which comprises the radiation-induced polymerisation, within the paper, of a vinyl monomer or a monomer mixture comprising one or more vinyl monomers, irradiation being carried out in the presence of the monomer or monomers, and the process being carried out in a substantially non-aqueous system.</p><p>In one preferred embodiment of the process ethyl acrylate is polymerised in the presence of methyl methacrylate as yield enhancer; in another preferred embodiment ethyl acrylate is used on its own, the treatment being repeated.</p><p>The polymerisation system may also contain a basic monomer like an amine-substituted alkyl methacrylate.</p> |
