摘要： A continuous process for the preparation of polyacetal copolymers from 1,3,5-trioxane and the comonomers known for this purpose using strong protic acids as an initiator, in which the initiator is added in an amount of 0.01 to 0.6 ppm, based on the total amount of monomers, in finely divided form to the monomer mixture, after the polymerization step the crude polymer is transferred from the polymerization reactor to a mixing unit without further intermediate steps, excess monomer is removed from the crude polymer in the mixing unit or between polymerization reactor and mixing unit by applying reduced pressure and, if desired, generally customary stabilizers, assistants, fillers, reinforcing materials and/or colorants are incorporated into the polymer in the mixing unit.

摘要： An inorganic, phosphate-containing cellular material is manufactured from Portland cement, polyphosphoric acid and an expanding agent acting in an acidic medium. There may be added furthermore aluminous cement, oxides of calcium, zinc, aluminum, iron, hydroxides of aluminum and iron, fillers and reinforcing agents. By intense intermixing of the starting products a mixture is prepared which has an equivalent ratio of (Al+Mg+CA+Fe) to phosphate of 0.8:1 to 3.0:1. The mixture foams, is charged to a mold, heated if necessary to a temperature of 80.degree. C., and after completed exothermal reaction hardened under heat.
