ABSTRACT:
A modified particle is disclosed wherein a particle has an attached group having the formula: ##STR1## wherein Ar represents an aromatic group; R.sup.1 represents a bond, an arylene group, an alkylene group ##STR2## wherein R.sup.4 is an alkyl or alkylene group or an aryl or arylene group; R.sup.2 and R.sup.3, which can be the same or different, represent hydrogen, an alkyl group, an aryl group, --OR.sup.5, --NHR.sup.5, --NR.sup.5 R.sup.5, or --SR.sup.5, wherein R.sup.5, which is the same or different, represents an alkyl group or an aryl group; and Q represents a labile halide containing species. Also disclosed is a modified particle or aggregate having attached a group having the formula: ##STR3## wherein CoupA represents a Si-containing group, a Ti-containing group, or a Zr-containing group; R.sup.8 and R.sup.9, which can be the same or different, represent hydrogen, an alkyl group, an aryl group, --OR.sup.10, --NHR.sup.10, --NR.sup.10 R.sup.10, or --SR.sup.10, wherein R.sup.10 represents an alkyl group or an aryl group; Q represents a labile halide containing species; and n is an integer of from 1 to 3. Modified particles with attached polymers are also disclosed as well as methods of making the modified particles.
