  • Titanate treated antimony compounds
    Patent number: 4100076
    Abstract: Finely divided particulate inorganic antimony compounds which are surface modified with an organic titanium compound having the formulaTi(OR).sub.4wherein each R is independently an alkyl, aryl, cycloalkyl, or vinyl group containing from one to about 18 carbon atoms, orTi(OR').sub.2 (OYX).sub.2wherein X is oxygen or nitrogen, Y is a two- or three-carbon atom chain, and R' is equal to R, H or the ligand represented by XYOH are described. These surface modified antimony compounds may be incorporated into various organic resin and elastomer systems to improve the flame-retardant properties of these materials.
    Type: Grant
    Filed: June 23, 1977
    Date of Patent: July 11, 1978
    Assignee: The Harshaw Chemical Company
    Inventors: John Slocum Ashman, Gerald Dennis Burt, Anton Mudrak
  • Zirconate treated antimony compounds
    Patent number: 4100077
    Abstract: Finely divided particulate inorganic antimony compounds which are surface-modified with an organic zirconate having the formula(RO).sub.4 Zrwherein each R is independently an aliphatic radical containing from one to about 18 carbon atoms are described. These surface-modified antimony compounds may be incorporated into various organic resin and elastomer systems to improve the flame-retardant properties of these materials.
