Abstract: PHOTOPOLYMERIZABLE COMPOSITIONS CONTAINING PHOROPOLYMERIZABLE ETHYLENICALLY UNSATURATED MONOMERIC COMPOUNDS, A POLYMER AS BINDER AND ALSO OZYPHOSPHORANES. THE ADDITION OF OXYPHOSPHORANES CONSIDERABLY IMPROVES THE PHOTOSENSITIVITY OF THE PHOTOPOLYMERIZABLE COMPOSITIONS AND THE CONSTANCY OF SAID SENSITIVITY EVEN WHEN THEY ARE STORED FOR PROLONGED PERIODS.

Abstract: The process of making poromeric materials which comprises impregnating webs of fibrous material with aqueous liquids containing olefinically unsaturated monomers which can be polymerized using redox catalysts, and, if desired, high polymeric plastics in dissolved, emulsified or dispersed form, freezing the webs of fibrous materials impregnated with the aqueous liquids, polymerizing the monomers using redox catalysts and thawing out and separating out the water and any residual monomer from the resulting poromeric materials. These poromeric materials are suitable as floor coverings, insulating materials, leather substitutes and coating materials.

Abstract: Production of poromeric materials by impregnating flat fibrous structures with liquids containing monoolefinically unsaturated monomers and high polymeric plastics in dissolved, emulsified or dispersed form, but no polyolefinically unsaturated monomers, freezing the impregnated fibrous structures, irradiating the frozen structures to effect polymerization of the monomers, and freeing the poromeric materials from the remaining liquid. The poromeric materials may be used as floor coverings, insulating materials, leather substitutes and coating materials.
