    摘要： A twin-screw machine used for treatment of plastics in which the screw shafts are fitted with eccentrically arranged kneading discs, the clearance .delta. between the kneading discs and the inner wall of the machine housing being greater than the constant clearance s between the particular adjacent kneading discs, and the eccentricity e, which is in each case of like orientation, between the axis of rotation and the central point of the kneading disc being greater than zero and less than half the absolute value of the difference between the housing and disc diameters minus the clearance s.

    摘要： Phosphoric acid triesters of the formula ##STR1## are produced in two or more stages by reacting phosphorus oxyhalides, phosphorus pentahalides, phosphoric acid monoester dihalides or phosphoric acid diester halides corresponding to the following general formula:ZO PO Hal.sub.2 (ZO).sub.2 PO Halwherein Z is defined as above and Hal represents Cl and/or Br with at least one hydroxyaryl compound of the formula ##STR2## in a two-phase mixture of an organic solvent an aqueous alkaline earth metal and/or alkali metal hydroxide solution.
