    摘要： A process for producing a polyamide or copolyamide freed from volatile constituents by removing the volatile constituents, in particular the monomers and dimers, in at least two stages from the polymer melt by using an, in particular, gaseous entrainer is described. The invention also relates to polyamide compositions made of polyamide 6 or a copolyamide with a reduced volatile constituent content, as well as moulding compositions made of the above-mentioned polyamides, and moulded articles and fibers which are produced from these moulding compositions.

    摘要： In a multilayer recording element which is suitable for producing flexographic printing plates by digital information transfer and has, arranged one on top of the other on a dimensionally stable substrate, a layer (A) which is crosslinkable by actinic radiation, a layer (B) sensitive to actinic radiation and, if required, a peelable cover sheet, the layer (A) crosslinkable by actinic radiation is crosslinked by imagewise exposure to actinic radiation of from 0.5 to 5 J/cm.sup.2 and can then be washed out by a developer and essentially comprises a mixture of at least one elastomeric binder, ethylenically unsaturated copolymerizable organic compounds, photoinitiator, and, if required, further assistants, and the layer (B) sensitive to actinic radiation is a layer which is soluble or dispersible in developers and has an optical density of >2.5 in the actinic range, undergoes a change the optical density by >1 as a result of one or more laser pulses in the wavelength range from 254 to 532 nm with an energy of from >5 to 50 J/cm.sup.2 and essentially comprises arylazophosphonate-containing compounds.
