    Abstract: Molding material comprising (a) a specially selected bitumen left as a residue in the distillation of petroleum which has been deacidified with calcium hydroxide and (b) an olefin polymer. The molding material may be pigment-colored and is used in the form of sheeting for insulation in construction.

    Abstract: PROBLEM TO BE SOLVED: To produce, by a single process, a fibrid that has high quality at low temperatures and is useful for paper, seals, friction brake lining, etc., by introducing a solution of a polyarylene ether in an appropriate solvent into a liquid solidifying medium under specific conditions. SOLUTION: This fibrid is obtained by introducing a solution of a polyarylene ether, such as polyarylene ether sulfone (preferably in concentration of 5-25wt.%) in an organic solvent, such as N-methylpyrrolidone and dimethylformamide, into a liquid solidifying medium while simultaneously giving the solution a shearing force so that a shearing space having an average energy density of 5W.s/cm or more is present during the introduction of the solution into the solidifying medium. In this case, the ratio by volume of the polymer solution to the solidifying medium is preferably in a range of from (1:10) to (1:20).

    Abstract: The invention relates to a continuous process for preparing aminoplastics and/or phenolics, in which a precondensate solution is prepared in a first extruder (14), the precondensate solution is continuously fed, with addition of additives, to a second extruder (20) with partial filling in the feed section (E) and devolatilization section (G), devolatilized in the second extruder (20) and then formed to give a molding composition or an end product. The process is particularly suitable for preparing melamine resins, in particular melamine-formaldehyde resins, as well as for preparing urea-formaldehyde resins.
