    摘要： A process for the treatment of archival material such as books and other bound volumes. The treatment includes a radiation-induced polymerization within the paper of the archival material of at least one mono-unsaturated vinyl monomer, selected from the esters of acrylic acid and .alpha.-lower alkyl-substituted acrylic acids, and at least one multi-unsaturated vinyl monomer. The process, which is carried out in a substantially non-aqueous solvent-free system, may be used to improve the structure of paper as well as to provide some protection against past and future degradation of the paper.

    摘要： A composition containing an aqueous, recycled cellulosic fibre pulp, print pigments contaminating the pulp, from 0.1% to 10% based on the weight of the pulp solids of a curable precursor of a solid polymer resin which is not substantive to the cellulosic fibres of the pulp, and a catalyst capable of curing the resin precursor in the dispersion; wherein the resin precursor contains a mixture of a fluid prepolymer having at least two reactive functional groups per molecule and a cross-linking agent capable of reacting with the functional groups.

    摘要： The method removes a contaminant, such as adhesive or ink particles, from wastepaper pulp. The method includes the steps of dispersing a monomer in the pulp so as to form droplets or beads which take up the particles e.g. by a process in which the particles are coated, absorbed or dissolved by, or adhere to the droplets or beads of monomer. The monomer is then polymerized to increase the rigidity of the droplets or beads, and the droplets or beads are separated from the pulp, e.g. by screening. The monomer or a mixtures of monomers are dispersed in the pulp by strong mechanical agitation and the agitation can be controlled to provide droplets or beads of monomer within a certain size range. Suitable monomers includes styrene, vinyl acetate, methyl methacrylate or mixtures of the same. The viscosity of the monomer phase may be increased by dissolving a homopolymer in the monomer to reduce the effect of shear forces caused by agitation. Benzoyl peroxide may be added to initiate polymerization.
