    摘要： The invention relates to a method for producing aqueous solutions of vinyl lactam polymers and solids obtainable therefrom by drying, particularly polyvinylpyrrolidone. Said method is characterised in that one or more sulphur components, selected from the group consisting of sulphur dioxide, sulphuric acid and one or more sulphuric acid salts, are used to reduce residual monomers. The invention also relates to vinyl lactam polymers that can be obtained using said method and which have good storage stability, and to the use of same, products and preparations which contain or have been produced using these vinyl lactam polymers.

    摘要： The invention relates to a radiation cross-linkable hot-melt adhesive, containing at least one poly(meth)acrylate, which can be radiation cross-linked and which is formed from C1 to C10 alkyl(meth)acrylates to at least 60 wt%, and at least one oligo(meth)acrylate, which contains non-acrylic C-C double bonds and has a K value of less than or equal to 20. The hot-melt adhesive contains a photoinitiator, which can be present as an additive not bonded to the poly(meth)acrylate and/or not bonded to the oligo(meth)acrylate, can be polymerized into the poly(meth)acrylate, and/or can be bonded to the oligo(meth)acrylate. The hot-melt adhesive can be used to produce adhesive tapes.
