Abstract
Finely divided particulate inorganic antimony compounds which are surface modified with up to about 5% by weight of an organosilane having the formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are each independently hydrogen, lower alkyl, lower alkenyl, alkoxyalkyl aryl, lower alkylaryl, or lower arylalkyl groups, and R' is an organo functional group 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.
