Abstract
According to the present invention a composition of matter is provided comprising the reaction product of a comminuted inorganic material and a substituted succinic anhydride having the formula: ##STR1## wherein at least one of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is a substituent selected from alkyl, alkenyl, alkynyl or aralkyl group having from 1 to about 30 carbon atoms or a substituted derivative thereof, and the remaining substituents are hydrogens. The substituent may be saturated or unsaturated, linear or branched, and may have from 1 to about 10 substitutions including halogen, tertiary amino, tertiary amide, ketal, episulfide, sulfonate, phosphonate, imide, carboxylate, carbonate, isocyanate, silane, epoxy, cyano, ether, thioether, carbonyl, aromatic nitro, or acetal. In a particular molecule, all of the R.sub.1, R.sub.2, R.sub.3 and R.sub.4 groups may be the same or different, so long as they fall within the above class.
