Abstract: The parts to be connected are first interlocked or held together by internal stresses, locked into the correct end position, to bring the joint surfaces into contact. They are then irradiated to melt them together, and the bond is cooled. Blunt contacting surfaces may be joined, avoiding irradiation of surrounding edge regions. Laser light with a wavelength between 0.5 and 10.90 mu m, pref. between 0.70 and 10.64 mu m is used. To weld non-thermoplastics, their joining surfaces are coated with thermoplastic.

Abstract: The use is disclosed of polymer mixtures for the production of moulded articles inscribed with the aid of high-energy radiation. The polymer mixtures in question contain the following basic components: a) 40-99 wt % - a polymer of a (meth)acrylic acid alkyl ester; b) 1-50 wt % - a copolymer of styrene- and acrylonitrile with an acrylonitrile content of 8-80 wt %; c) 0-50 wt % - an unvulcanized rubber; d) 0-20 wt % - additives and auxiliary products.

Abstract: The invention relates to compositions which are storage-stable at room temperature and which can be heat-cured to form molded parts having polyurethane, polyurea, and polyisocyanurate groups, said composition containing (a) one or more polyols having a molecular weight of from 400 to 10,000 and a functionality of from 2 to 8, (b) at least one polyfunctional compound having a molecular weight of 62 to 400 and being selected from the group consisting of aliphatic hydroxyl compound, cycloaliphatic hydroxyl compounds, aromatic amino compounds, or mixtures thereof, and (c) an organic polyisocyanate which is present in the form of discrete particles, which are deactivated on their surfaces and are dispersed in the liquid component, and depending on the product needs, (d) catalysts, (e) blowing agents, (f) reinforcing materials, and (g) auxiliaries and additives, The single-component systems are used for the preparation of cellular or noncellular, optionally reinforced polyurethane, polyurea, and/or polyisocyanurate group-containing molded parts.
