PARTICULATE POWDER OF HYDROTALCITE TYPE COMPOUND, CHLORINATED-RESIN STABILIZER COMPRISING THE PARTICULATE POWDER OF HYDROTALCITE TYPE COMPOUND, AND CHLORINATED-RESIN COMPOSITION

摘要

A particulate powder of an Mg-Al or Mg-Zn-Al hydrotalcite type compound, characterized by having a total content of soluble anions of 70 ppm or lower; a chlorinated-resin stabilizer for stabilizing a chlorinated-resin composition, the stabilizer comprising the particulate powder; and a chlorinated-resin composition comprising a chlorinated resin and the particulate powder contained therein. The particulate powder can be produced by yielding and aging hydrotalcite type compound particles, regulating the pH of the resultant slurry to 9.5-12, and then cleaning and drying the particles.
