Claims24
A modified particle comprising a particle having attached a group having the formula:
- wherein A represents at least one aromatic group or at least one alkyl group;
- R1 represents a bond, an arylene group, an alkylene group,
- wherein R4 is an alkyl or alkylene group or an aryl or arylene group;
- R2 and R3, which can be the same or different, represent hydrogen, an alkyl group, an aryl group, —OR5, —NHR5, —NR5R5, or —SR5, wherein R5, which is the same or different, represents an alkyl group or an aryl group;
- Q represents a labile halide containing species and X represents a polymer formed from at least one polymerizable monomer.
A modified particle or aggregate comprising a) an aggregate comprising at least one carbon phase and at least one metal-containing species phase, an aggregate comprising at least one carbon phase and at least one silicon-containing species phase, a metal oxide, or a metal hydroxide and b) attached to said particle or aggregate a group having the formula:
- wherein CoupA represents a Si-based group, a Ti-based group, a Cr-based group, or a Zr-based group;
- R8 and R9, which can be the same or different, represent hydrogen, an alkyl group, an aryl group, —OR10, —NHR10, —NR10R10, or —SR10, wherein R10, which is the same or different, represents an alkyl group or an aryl group;
- Q represents a labile halide containing radical;
- X represents a polymer formed from at least one polymerizable monomer;
- and n is an integer of from 1 to 3.
