    摘要: HEXAGONAL SYSTEM PRISMATIC CALCIUM SULFITE, WHICH IS USEFUL AS A FILLER FOR THERMOPLASTIC RESINS, IN PREPARED BY CONTACTIG AN SO2-CONTAINING GAS WITH A SUSPENSION OF CALCIUM HYDROXIDE, PRECIPITATED CALCIUM CARBONATE, OR MIXTURES THEREOF WHEREIN THE SO2-CONTAINING GAS IS PASSED CONTINUOUSLY THROUGH A PLURALITY OF CONTACT ZONES IN WHICH THE FIRST OF SAID ZONES HAS A TEMPERATURE OF 50*-100*C. AND A PH OF 3-6 AND EACH SUCCEEDING CONTACT ZONE HAS A TEMPERATURE OF 50*-100*C. AND A PH OF HIGHER THAN 6, WHILE SIMULTANEOUSLY PASSING THE SUSPENSION THROUGH SAID PLURALITY OF CONTACT ZONES COUNTER-CURRENTLY TO THE DIRECTION OF THE FLOW OF THE SO2-CONTAINING GAS.

    摘要: A method for the preparation of a filler to be used with thermoplastic resins comprising a process of making the mixture of two or three members selected from the group consisting of sulfur dioxide, sulfur trioxide and carbon dioxide act on calcium hydroxide in the presence of water or a process of making either sulfur dioxide or sulfur trioxide or the mixture thereof act on calcium carbonate in the presence of water. Thermoplastic compositions containing the coprecipitated filler mixture have superior physical characteristics when compared to thermoplastic compositions which contain filler mixtures mechanically mixed.
