| abstract |
The present invention is method of making a metal, metal oxide, or metal hydroxide filler composition by dry coating powders with an polymerizable monomers using a coupling agent, preferably an trialkoxysilane, as a covalent linker between the filler and the monomer coating, and inducing polymerization to provide polymer coated particles of the powders. The invention also includes novel compositions comprising metal, metal oxide and hydroxide powders with bonded coupling agent and polymer coatings. |
