Abstract
A mineral particulate is disclosed selected from the group consisting of metal carbonates, glass fibers and layered lattice silicates, comprising particles of said mineral, the surface of which have been modified by a polymer synthesized in situ in the presence of a reactive gas selected from the group consisting of hydrogen, carbon monoxide and carbon dioxide; said particulate having a predetermined particle size distribution which substantially corresponds to the particle size distribution of the surface-unmodified feed particulate from which the product particulate is produced.
