Abstract
Disclosed is a coated particulate flame retardant for a polymer, which comprises inorganic compound particles, each having, bonded to the surface thereof through a covalent bond, a coating compound so that the inorganic compound particle is coated with the coating compound, wherein the coated inorganic compound particles have an in situ-found number average particle diameter (α) in the range of from 1 to 1,000 nm, as measured with respect to the coated inorganic compound particles in a composition comprising a polymer having dispersed therein the coated inorganic compound particles.
